1960s and 1970s
In the very late 1960s and 1970s, rock and roll turned into a harder, louder form of music called rock. In the 1970s, rock music bands played huge, loud concerts in outdoor stadiums. In the early 1970s, many rock bands played psychedelic rock, a type of rock music with lyrics and sounds that were intended to give the listener some idea of what it felt like to be on so-called "mind-expanding" (and usually illegal) drugs, and which some believe even enhanced the experience of being on the drugs themselves. Many bands from Britain played blues music mixed with rock music, such as The Animals, The Kinks, The Who, Jimi Hendrix, the
Jeff Beck Group.
In the late 1960s, a harder form of rock music called "heavy metal" was invented. The first use of the term was in a 1968 song by Steppenwolf, "Born to be Wild", and other early heavy metal bands appeared in the same year. Black Sabbath was the band that invented metal music in the late 1960s, the band played loud, hard rock music based on blues music. Heavy metal music was mostly based on the sounds of the electric guitar. The electric guitar in heavy metal is always amplified through powerful amplifiers so that it has a loud, distorted, angry sound. Other bands such Deep Purple, Black Sabbath, Judas Priest, Eric Burdon and Alice Cooper played even louder, harder forms of heavy metal rock music.
Many debate who came first, Motorhead or Black Sabbath, however it is generally accepted in the metal community that either / or created heavy metal.
In the 1980s more sub-genre's of Heavy Metal bands were created, one of which was "Hair-Metal" with Bands such as Mötley Crüe, W.A.S.P. and
Ratt became popular. Heavy Metal rock bands had long hair and the men wore make up (lipstick and eyeshadow) and tight leather pants and boots. Many metal songs were about love, sex, partying, having a good time, illegal drug use, and drinking alcohol. Rarely,but sometimes, metal songs were also politically and socially critical. In the late 1980s, groups such as Poison and Warrant were very successful, smashing the field with songs like “Talk Dirty to Me,” and “Cherry Pie.”
Another type of heavy metal in the 1980s was called "thrash metal" or "thrash." Thrash metal bands played a faster, more aggressive type of heavy metal rock. Thrash metal bands such as Metallica, Megadeth, Anthrax and Slayer had many fans.
In the 1990s, a new form of heavy metal developed, called alternative metal. Alternative metal combined thrash metal and grunge rock with hip-hop music and industrial music.
Also in the 1990s was nu metal, a shortening of "new metal". Nu metal mixed
rap and hip hop style singing with metal music. Nu metal bands also often include DJ decks, synthesizers and other electronic instruments. Nu metal was very successful and made a lot of money, especially bands such as Linkin Park, Limp Bizkit and Slipknot as well as Disturbed.
Two other styles of heavy metal music, "death metal" and "black metal" are very angry, fast music. A person who does not like heavy metal at all will have a much harder time listening to death metal or black metal because it is much faster, louder, and more aggressive than other types of music. The singers usually do not sing, but instead they growl or roar to make the songs more intense. This makes it harder to hear the lyrics (words) and most people are not used to singers who use their voice in this way. The lyrics often tell stories from the view of people who are suffering and dying, or people who are hurting others. The guitars are usually distorted. The drums also use very fast beats with double bass pedals (AKA two kick pedals, double peds, etc.)
Other important styles of metal are: power metal, a style whose music often is about fiction and epics like The Lord of the Rings, and gothic metal, which has melancholy songs about abstract subjects like pain, life, death, faith and religion.
