^ From late 2010 until his death in May 2013, Jeff Hanneman's participation in Slayer was minimal. In January 2011, he contracted necrotizing fasciitis, which severely restricted his ability to perform. He appeared publicly with the band on only one known occasion, playing two songs during an encore at one of Slayer's Big 4 performances in April 2011; he also attended rehearsals for Fun Fun Fun Fest in November 2011, but did not end up performing at this show. By July 2012, Hanneman had not written or recorded any new material for the band's follow up to 2009's World Painted Blood. In February 2013, Kerry King stated he was planning on recording all of the guitar parts for the upcoming album himself, but was open to Hanneman's return if he was willing and able. King also denied that Gary Holt, member of Exodus and Hanneman's live fill-in, would write or record anything for the upcoming album. Hanneman died on May 2, 2013 at the age of 49 due to liver failure.
