Early years (1981–1983)
Slayer was formed in 1981 by Kerry King, Jeff Hanneman, Dave Lombardo, and Tom Araya. The group started out playing covers of songs by bands such as Iron Maiden and Judas Priest at parties and clubs in Southern California. The band's early image relied heavily on Satanic themes that featured pentagrams, make-up, spikes, and inverted crosses. Rumors that the band was originally known as Dragonslayer, after the 1981 movie of the same name, were denied by King, as he later stated: "We never were; it's a myth to this day."
In 1983, Slayer was invited to open for the band Bitch at the Woodstock Club in Anaheim, California to perform eight songs, six of which were covers. The band was spotted by Brian Slagel, a former music journalist who had recently founded Metal Blade Records. Impressed with Slayer, he met with the band backstage and asked them to record an original song for his upcoming Metal Massacre III compilation album. The band agreed and their song "Aggressive Perfector" created an underground buzz upon its release in mid 1983, which led to Slagel offering the band a recording contract with Metal Blade.
Show No Mercy, Haunting the Chapel and Hell Awaits (1983–1986)
was the guitarist of Slayer for 30 years, from 1981 to 2011. He was the main songwriter along with Kerry King, as well as a lyricist.
Without any recording budget, the band had to self-finance its debut album. Combining the savings of Araya, who was employed as a respiratory therapist, and money borrowed from King's father, the band entered the studio in November 1983. The album was rushed into release, stocking shelves three weeks after tracks were completed. Show No Mercy, released in December 1983 by Metal Blade Records, generated underground popularity for the band. The group began a club tour of California to promote the album. The tour gave the band additional popularity and sales of Show No Mercy eventually reached more than 20,000 in the US and another 20,000 worldwide.
In February 1984, King briefly joined Dave Mustaine's new band Megadeth. Hanneman was worried about King's decision, stating in an interview, "I guess we're gonna get a new guitar player." While Mustaine wanted King to stay on a permanent basis, King left after five shows, stating Mustaine's band was "taking too much of my time." The split caused a rift between King and Mustaine, which evolved into a long running feud between the two bands.
In June 1984, Slayer released a three-track EP called Haunting the Chapel. The EP featured a darker, more thrash-oriented style than Show No Mercy, and laid the groundwork for the future direction of the band. The opening track, "Chemical Warfare", has become a live staple, played at nearly every show since 1984.
Later that year, Slayer began their first national club tour, traveling in Tom Araya's Camaro towing a U-Haul trailer. The band recorded the live album Live Undead in November 1984 while in New York City.
In March 1985, Slayer began a national tour with Venom and Exodus, resulting in their first live home video dubbed Combat Tour: The Ultimate Revenge. The video featured live footage filmed at the Studio 54 club. The band then made its live European debut at the Heavy Sound Festival in Belgium opening for UFO.
By 1985, Show No Mercy had sold over 40,000 copies, which led to the band returning to the studio to record their second full-length album. Metal Blade financed a recording budget, which allowed the band to hire producer Ron Fair. Released in September 1985, Slayer's second full-length album, Hell Awaits, expanded on the darkness of Haunting the Chapel, with hell and Satan as common song subjects. The album was the band's most progressive offering, featuring longer and more complex song structures. The intro of the title track is a backwards recording of a demonic-sounding voice repeating "Join us", ending with "Welcome back" before the track begins. The album was a hit, with fans choosing Slayer for best band, best live band, Hell Awaits, as 1985's best album, and Dave Lombardo as best drummer in the British magazine Metal Forces' 1985 Readers Poll.
Reign in Blood (1986–1987)
Guitarist Kerry King
is one of the two constant members of Slayer.
Following the success of Hell Awaits, Slayer was offered a recording contract with Russell Simmons and Rick Rubin's newly founded Def Jam Records, a largely hip hop-based label. The band accepted, and with an experienced producer and major label recording budget, the band underwent a sonic makeover for their third album Reign in Blood, resulting in shorter, faster songs with clearer production. The complex arrangements and long songs featured on Hell Awaits were ditched in favor of stripped down, hardcore punk influenced song structures.
Def Jam's distributor, Columbia Records, refused to release the album due to the song “Angel of Death” which detailed Holocaust concentration camps and the human experiments conducted by Nazi physician Josef Mengele. The album was distributed by Geffen Records on October 7, 1986. However, due to the controversy, Reign in Blood did not appear on Geffen Records' release schedule. Although the album received virtually no radio airplay, it became the band's first to enter the Billboard 200, debuting at number 94, and the band's first album certified gold in the United States.
In October 1986, Slayer embarked on the Reign in Pain world tour, with Overkill in the US, and Malice in Europe. The band was added as the opening act on W.A.S.P.'s US tour, but just one month into it, drummer Lombardo left the band: "I wasn't making any money. I figured if we were gonna be doing this professionally, on a major label, I wanted my rent and utilities paid." To continue with the tour, Slayer enlisted Tony Scaglione of Whiplash. However, Lombardo was convinced by his wife to return in 1987. At the insistence of Rubin, Slayer recorded a cover version of Iron Butterfly's "In-A-Gadda-Da-Vida" for the film Less Than Zero. Although the band was not happy with the final product, Hanneman deeming it "a poor representation of Slayer" and King labeling it "a hunk of shit", it was one of their first songs to garner radio airplay.
South of Heaven and Seasons in the Abyss (1988–1993)
In late 1987, Slayer returned to the studio to record their fourth studio album. To contrast the speed of Reign in Blood, the band consciously decided to slow down the tempos, and incorporate more melodic singing. According to Hanneman, "We knew we couldn't top Reign in Blood, so we had to slow down. We knew whatever we did was gonna be compared to that album, and I remember we actually discussed slowing down. It was weird—we've never done that on an album, before or since."
Released in July 1988, South of Heaven received mixed responses from both fans and critics, although it was Slayer's most commercially successful release at the time, debuting at number 57 on the Billboard 200, and their second album to receive gold certification in the United States. Press response to the album was mixed, with AllMusic citing the album as "disturbing and powerful", and Kim Nelly of Rolling Stone calling it "genuinely offensive satanic drivel". King said "that album was my most lackluster performance", although Araya called it a "late bloomer" which eventually grew on people.
Slayer returned to the studio in spring 1990 with co-producer Andy Wallace to record its fifth studio album. Following the backlash created by South of Heaven, Slayer returned to the "pounding speed of Reign in Blood, while retaining their newfound melodic sense." Seasons in the Abyss, released on October 25, 1990, was the first Slayer album to be released under Rubin's new Def American label, as he had parted ways with Def Jam owner Russell Simmons over creative differences. The album debuted at number 44 on the Billboard 200, and was certified gold in 1992. The album spawned Slayer's first music video for the album's title track, which was filmed in front of the Giza pyramids in Egypt.
Slayer returned as a live act in September 1990 to co-headline the European Clash of the Titans tour with Megadeth, Suicidal Tendencies, and Testament. During the sold out European leg of this tour, tickets had prices skyrocket to 1,000 Deutschmark (US$680) on the black market. With the popularity of American thrash at its peak, the tour was extended to the US beginning in May 1991, with Megadeth, Anthrax, and opening act Alice in Chains. The band released a double live album, Decade of Aggression in 1991, to celebrate ten years since their formation. The compilation debuted at number 55 on the Billboard 200.
In May 1992, Lombardo left the band due to conflicts with the other members, as well as his desire to be off tour for the birth of his first child. Lombardo formed his own band Grip Inc., with Voodoocult guitarist Waldemar Sorychta, and Slayer recruited former Forbidden drummer Paul Bostaph to fill in the drummer position. Slayer made its debut appearance with Bostaph at the 1992 Monsters of Rock festival at Castle Donington. Bostaph's first studio effort was a medley of three Exploited songs, "War", "UK '82", and "Disorder", with rapper Ice-T, for the Judgment Night movie soundtrack in 1993.
Divine Intervention and Undisputed Attitude (1994–1997)
Bassist/vocalist Tom Araya
is one of the two constant members of Slayer.
In 1994, Slayer released Divine Intervention, the band's first album with Bostaph on the drums. The album featured songs about Reinhard Heydrich, an architect of the Holocaust, and Jeffrey Dahmer, an American serial killer and sex offender. Other themes included murder, the evils of church, and the lengths to which governments went to wield power, Araya's interest in serial killers inspired much of the content of the lyrics.
Slayer geared up for a world tour in 1995, with openers Biohazard and Machine Head. A video of concert footage, Live Intrusion was released, featuring a joint cover of Venom's "Witching Hour" with Machine Head. Following the tour, Slayer was billed third at the 1995 Monsters of Rock festival, headlined by Metallica. In 1996, Undisputed Attitude, an album of punk covers, was released. The band covered songs by Minor Threat, T.S.O.L., Dirty Rotten Imbeciles, D.I., Verbal Abuse, Dr. Know, and The Stooges. The album featured three original tracks, "Gemini", "Can't Stand You", "Ddamm"; the latter two were written by Hanneman in 1984–1985 for a side project entitled Pap Smear. Bostaph left Slayer shortly after the album's recording to work on his own project, Truth About Seafood. With Bostaph's departure, Slayer recruited Testament drummer Jon Dette, and headlined the 1996 Ozzfest alongside with Ozzy Osbourne, Danzig, Biohazard, Sepultura, and Fear Factory. Dette was fired after a year, due to a fallout with band members. After that, Bostaph returned to continue the tour.
Diabolus in Musica (1998–2000)
Diabolus in Musica (Latin for "The Devil in Music") was released in 1998, and debuted at number 31 on the Billboard 200, selling over 46,000 copies in its first week. The album received a mixed critical reception, and was criticized for adopting characteristics of nu metal music such as tuned down guitars, murky chord structures, and churning beats. Blabbermouth.net reviewer Borijov Krgin described the album as "a feeble attempt at incorporating updated elements into the group's sound, the presence of which elevated the band's efforts somewhat and offered hope that Slayer could refrain from endlessly rehashing their previous material for their future output", while Ben Ratliff of The New York Times had similar sentiments, writing on June 22, 1998 that: "Eight of the 11 songs on Diabolus in Musica, a few of which were played at the show, are in the same gray key, and the band's rhythmic ideas have a wearying sameness too."
The album was the band's first to primarily feature dropped tuning, as featured on the lead track, "Bitter Peace", making use of the tritone interval referred to in the Middle Ages as the Devil's interval. Slayer teamed up with digital hardcore group Atari Teenage Riot to record a song for the Spawn soundtrack titled "No Remorse (I Wanna Die)". The band paid tribute to Black Sabbath by recording a cover of "Hand of Doom" for the second of two tribute albums, titled Nativity in Black II. A world tour followed to support the new album, with Slayer making an appearance at the United Kingdom Ozzfest 1998 alongside Black Sabbath, Ozzy Osbourne, Foo Fighters, Pantera, Soulfly, Fear Factory, and Therapy?.
God Hates Us All (2001–2005)
After delays regarding remixing and artwork, including slip covers created to cover the original artwork as it was deemed "too graphic", Slayer's next album, God Hates Us All, was released on September 11, 2001. The band received its first Grammy nomination for the lead track "Disciple", although the Grammy was awarded to Tool, for "Schism". The September 11 attacks on America jeopardized the 2001 European tour Tattoo the Planet originally set to feature Pantera, Static-X, Cradle of Filth, Biohazard and Vision of Disorder. The dates in the United Kingdom were postponed due to flight restrictions, with a majority of bands deciding to withdraw, leaving Slayer and Cradle of Filth remaining for the European leg of the tour.
Pantera, Static-X, Vision of Disorder and Biohazard were replaced by other bands depending on location; Amorphis, In Flames, Moonspell, Children of Bodom, and Necrodeath. Biohazard eventually decided to rejoin the tour later on, and booked new gigs in the countries, where they missed a few dates. Drummer Bostaph left Slayer before Christmas in 2001, due to a chronic elbow injury, which would hinder his ability to play. Slayer's "God Hates Us All" tour was unfinished so Manager, Rick Sales, contacted original drummer Lombardo, and asked if he would like to finish the remainder of the tour. Lombardo accepted the offer, and stayed as a permanent member.
Slayer toured playing Reign in Blood in its entirety throughout the fall of 2003, under the tour banner "Still Reigning". Their playing of the final song, "Raining Blood", culminated with the band drenched in a rain of stage blood. Live footage of this was recorded at the Augusta Civic Center in Augusta, Maine, on July 11, 2004 and released on the 2004 DVD Still Reigning. The band also released War at the Warfield and a box set, Soundtrack to the Apocalypse featuring rarities, live CD and DVD performances and various Slayer merchandise. From 2002 to 2004, the band performed over 250 tour dates, headlining major music festivals including H82k2, Summer tour, Ozzfest 2004 and a European tour with Slipknot. While preparing for the Download Festival in England, Metallica drummer Lars Ulrich was taken to a hospital with an unknown and mysterious illness, and was unable to perform. Metallica vocalist James Hetfield searched for volunteers at the very last minute to replace Ulrich; Lombardo and Slipknot drummer Joey Jordison volunteered, with Lombardo performing the songs "Battery" and "The Four Horsemen".
Christ Illusion (2006–2008)
The next studio album, Christ Illusion, was originally scheduled for release on June 6, 2006, and would be the first album with original drummer Lombardo since 1990's Seasons in the Abyss. However, the band decided to delay the release of the record, as they did not want to be among the many, according to King, "half-ass, stupid fucking loser bands" releasing records on June 6, although USA Today reported the idea was thwarted because the band failed to secure sufficient studio recording time. Slayer released Eternal Pyre on June 6 as a limited-edition EP. Eternal Pyre featured the song "Cult", a live performance of "War Ensemble" in Germany and video footage of the band recording "Cult". Five thousand copies were released and sold exclusively through Hot Topic chain stores, and sold out within hours of release. On June 30, Nuclear Blast Records released a 7" vinyl picture disc version limited to a thousand copies.
Christ Illusion was released on August 8, 2006, and debuted at number 5 on the Billboard 200, selling over 62,000 copies in its first week. The album became Slayer's highest charting, improving on its previous highest charting album, Divine Intervention, which had debuted at number 8. However, despite its high positioning, the album dropped to number 44 in the following week. Three weeks after the album's release Slayer were inducted into the Kerrang! Hall of Fame for their influence to the heavy metal scene.
A worldwide tour dubbed The Unholy Alliance Tour, was undertaken to support the new record. The tour was originally set to launch on June 6, but was postponed to June 10, as Araya had to undergo gall bladder surgery. In Flames, Mastodon, Children of Bodom, Lamb of God, and Thine Eyes Bleed (featuring Araya's brother, Johnny) and Ted Maul (London Hammersmith Apollo) were supporting Slayer. The tour made its way through America and Europe and the bands who participated, apart from Thine Eyes Bleed, reunited to perform at Japan's Loudpark Festival on October 15, 2006.
The video for the album's first single, "Eyes of the Insane", was released on October 30, 2006. The track was featured on the Saw III soundtrack, and won a Grammy-award for "Best Metal Performance" at the 49th Grammy Awards, although the band was unable to attend due to touring obligations. A week later, the band visited the 52nd Services Squadron located on the Spangdahlem U.S. Air Force Base in Germany to meet and play a show. This was the first visit ever to a military base for the band. The band made its first network TV appearance on the show Jimmy Kimmel Live! on January 19, playing the song "Eyes of the Insane", and four additional songs for fans after the show (although footage from "Jihad" was cut due to its controversial lyrical themes).
Slayer toured Australia and New Zealand in April with Mastodon, and appeared at the Download Festival, Rock Am Ring, and a Summer tour with Marilyn Manson and Bleeding Through. The band released a special edition of Christ Illusion, which featured new cover art and bonus track, "Final Six", which was given a Grammy Award for "Best Metal Performance". This is the band's second consecutive award in that category.
World Painted Blood (2009–2011)
In 2008, Araya stated uncertainty about the future of the band, and that he could not see himself continuing the career at a later age. He said that once the band finished its upcoming album, which was the final record in their contract, the band would sit down and discuss its future. King was optimistic that the band would produce at least another two albums before considering to disband: "We're talking of going in the studio next February  and getting the next record out so if we do things in a timely manner I don't see there's any reason why we can't have more than one album out." Slayer, along with Trivium, Mastodon, and Amon Amarth, teamed up for a European tour titled 'The Unholy Alliance: Chapter III', throughout October and November 2008. Slayer headlined the second Mayhem Festival in the summer of 2009. Slayer, along with Megadeth, also co-headlined Canadian Carnage, the first time they performed together in more than 15 years when they co-headlined four shows in Canada in late June 2009 with openers Machine Head and Suicide Silence.
The band's tenth studio album, World Painted Blood, was released by American Recordings. It was available on November 3 in North America and November 2 for the rest of the world. The band stated that the album takes elements of all their previous works including Seasons in the Abyss, South of Heaven, and Reign in Blood. Slayer, along with Metallica, Megadeth, and Anthrax performed on the same bill for the first time on June 16, 2010 at Bemowo Airport, near Warsaw, Poland. One of the following Big 4 performances in (Sofia, Bulgaria, June 22, 2010) was sent via satellite in HD to cinemas. They also went on to play several other dates as part of the Sonisphere Festival. Megadeth and Slayer joined forces once again for the American Carnage Tour from July to October 2010 with opening acts Anthrax and Testament, and European Carnage Tour in March and April 2011. The "Big Four" played more dates at Sonisphere in England and France for the first time ever. Slayer returned to Australia in February and March 2011 as part of the Soundwave Festival and also played in California with the other members of the "Big Four".
In early 2011, Hanneman was diagnosed with necrotizing fasciitis. According to the band, doctors said that it likely originated from a spider bite. Araya said of Hanneman's condition: "Jeff was seriously ill. Jeff ended up contracting a bacteria that ate away his flesh on his arm, so they cut open his arm, from his wrist to his shoulder, and they did a skin graft on him, they cleaned up ... It was a flesh-eating virus, so he was really, really bad. So we'll wait for him to get better, and when he's a hundred percent, he's gonna come out and join us." The band decided to play their upcoming tour dates without Hanneman. Gary Holt of Exodus was announced as Hanneman's temporary replacement. Cannibal Corpse guitarist Pat O'Brien filled in for Holt during a tour in Europe. On April 23, 2011, at the American Big 4 show in Indio, California, Hanneman rejoined his bandmates to play the final two songs of their set, "South of Heaven" and "Angel of Death". This turned out to be Hanneman's final live performance with the band.
Death of Jeff Hanneman, departure of Dave Lombardo, and Repentless (2011–2016)
When asked if Slayer would make another album, Lombardo replied "Yes absolutely; Although there's nothing written, there are definitely plans." However, Araya said Slayer would not begin writing a new album until Hanneman's condition improved. To celebrate the 25th anniversary of Reign In Blood, the band performed all of the album's tracks at the All Tomorrow's Parties festival at the Alexandra Palace in London.
In November 2011, Lombardo posted a that the band had started to write new music. This presumably meant that Hanneman's condition improved, and it was believed he was ready to enter the studio. King had worked with Lombardo that year and they completed three songs. The band planned on entering the studio in either March or April 2012 and were hoping to have the album recorded before the group's US tour in late May and release it by the summer of that year. However, King said the upcoming album would not be finished until September and October of that year, making a 2013 release likely. In July 2012, Kerry King revealed two song titles for the upcoming album, "Chasing Death" and "Implode".
In February 2013, Lombardo was fired right before Slayer was to play at Australia's Soundwave festival due to an argument with band members over a pay dispute. Slayer and American Recordings released a statement, saying "Mr. Lombardo came to the band less than a week before their scheduled departure for Australia to present an entirely new set of terms for his engagement that were contrary to those that had been previously agreed upon", although Lombardo claimed there was a gag order in place. Jon Dette returned to fill in for Lombardo for the Soundwave dates. It was confirmed that Lombardo was officially out of Slayer for the third time, and, when in May, Paul Bostaph rejoined the band.
guitarist Gary Holt
joined Slayer in 2011, originally as a touring member, and later became an official replacement for Jeff Hanneman
, who died in 2013.
On May 2, 2013, Jeff Hanneman died due to liver failure in a local hospital near his home in Southern California's Inland Empire; the cause of death was later determined to be alcohol-related cirrhosis. King confirmed that the band would continue, saying "Jeff is going to be in everybody's thoughts for a long time. It's unfortunate you can't keep unfortunate things from happening. But we're going to carry on – and he'll be there in spirit." However, Araya felt more uncertain about the band's future, expressing his belief that "After 30 years [with Hanneman active in the band], it would literally be like starting over", and doubting that Slayer's fanbase would approve such a change. Despite the uncertainty regarding the band's future, Slayer still worked on a followup to World Painted Blood. Additionally, it was reported that the new album would still feature material written by Hanneman.
At the 2014 Revolver's Golden Gods Awards ceremony, Slayer debuted "Implode", its first new song in five years. The group announced that they have signed with Nuclear Blast, and planned to release a new album in 2015. It was reported that Holt would take over Hanneman's guitar duties full-time, although Holt did not participate in the songwriting. In February, Slayer announced a seventeen date American tour to start in June featuring Suicidal Tendencies and Exodus. In 2015, Slayer headlined the Rockstar Energy Mayhem Festival for the second time. Repentless, the band's twelfth studio album, was released on September 11, 2015. Slayer toured for two-and-a-half years in support of Repentless. The band toured Europe with Anthrax and Kvelertak in October and November 2015, and embarked on three North American tours: one with Testament and Carcass in February and March 2016, then with Anthrax and Death Angel in September and October 2016, and with Lamb of God and Behemoth in July and August 2017. A lone date in Southeast Asia in 2017 was held in the Philippines.
Cancelled thirteenth studio album and farewell tour (2016–present)
In August 2016, guitarist Kerry King was asked if Slayer would release a follow-up to Repentless. He replied, "We've got lots of leftover material from the last album, 'cause we wrote so much stuff, and we recorded a bunch of it too. If the lyrics don't change the song musically, those songs are done. So we are way ahead of the ballgame without even doing anything for the next record. And I've been working on stuff on my downtime. Like, I'll warm up and a riff will come to mind and I'll record it. I've gotten a handful of those on this run. So wheels are still turning. I haven't worked on anything lyrically yet except for what was done on the last record, so that's something I've gotta get on. But, yeah, Repentless isn't quite a year old yet." King also stated that Slayer was not expected to enter the studio until at least 2018. In an October interview on Hatebreed frontman Jamey Jasta's podcast, King stated that he was "completely open" to having guitarist Gary Holt (who had no songwriting contributions on Repentless) involved in the songwriting process of the next Slayer album. He explained, "I'm entirely open to having Gary work on something. I know he's gotta work on an Exodus record and I've got tons already for this one. But, you know, if he's gonna stick around... I didn't want it on the last one, and I knew that. I'm completely open to having that conversation. I haven't talked to Tom about it, I haven't talked to Gary open about it, but I'm open. That's not saying it is or isn't gonna happen. But my ears are open."
In a June 2017 interview with the Ultimate Guitar Archive, Holt said that he was ready to contribute with the songwriting for the next album. When speaking to Revolver, King was asked if there were any plans in place for the band to begin working on the album, he said, "Funny thing is, Repentless isn't even two years old yet, though it seems like it is. But from that session, there are six or eight songs that are recorded—some with vocals, some with leads, but all with keeper guitar, drums and bass. So when those songs get finished lyrically, if the lyrics don't change the songs, they'll be ready to be on the next record. So we already have more than half a record complete, if those songs make it." He also gave conceivable consideration that it could be released next year, "I'm certainly not gonna promise it, because every time I do, I make a liar of myself! [Laughs]" When asked about any plans or the timeline the band would like to release the album, King said, "It depends on touring—getting time to rehearse, getting time to make up new stuff. We haven't even done Australia on this run yet at all. We're hitting Japan finally later this year. But if things go well, I'd like to record next year. But timelines change all the time." In an October 2017 interview, Holt once again expressed his desire to contribute to the songwriting for the next Slayer album, saying, "When that time comes and we are ready for the next album, if Kerry wants me to contribute, I've got riffs. I've got stuff right now that I've written that I am not using for Exodus, because it was kind of maybe just unintentional subconscious thing, like, 'It sounds a little too Slayer.'"
On January 22, 2018, Slayer announced their farewell world tour, which began with a North American trek in May and June, supported by Lamb of God, Anthrax, Behemoth and Testament. The second leg of the North American tour took place in July and August, with Napalm Death replacing Behemoth, followed in November and December by a European tour with Lamb of God, Anthrax and Obituary. The farewell tour continued into 2019, with plans to visit places such as South America, Australia and Japan; in addition to European festivals such as Hellfest and Graspop, the band toured the United States in May 2019 with Lamb of God, Amon Amarth and Cannibal Corpse. Slayer also played one show in Mexico at Force Fest in October 2018.
On December 2, 2018, Holt announced that he would not perform the remainder of the band's European tour to be with his dying father. Vio-lence and former Machine Head guitarist Phil Demmel would fill in for him as a result.
Holt had stated that Slayer would not release a new album before the group's disbandment. On how long the farewell tour would last, Holt's Exodus bandmate Steve "Zetro" Souza commented, "I'm speculating it's gonna take a year and a half or two years to do the one final thing, but I believe it's finished. Everybody knows what I know; just because I'm on the outside, I have no insight on that." The final North American leg of the tour, dubbed "The Last Campaign", will take place in November 2019, and will also include support from Primus, Ministry and Philip H. Anselmo & The Illegals.
