Slayer is an American thrash metal band from Huntington Park, California, formed in 1981 by guitarists Kerry King and Jeff Hanneman, drummer Dave Lombardo and vocalist/bassist Tom Araya. Slayer's fast and aggressive musical style made them one of the "big four" bands of thrash metal, alongside Metallica, Megadeth, and Anthrax. Slayer's current lineup comprises King, Araya, drummer Paul Bostaph, and guitarist Gary Holt, who initially joined as a touring musician in 2011 before joining the band permanently after Hanneman's death in 2013; the drummer Jon Dette is a former member of the band.
