Corrosion of Conformity is an American heavy metal band from Raleigh, North Carolina, formed in 1982. The band has undergone multiple lineup changes throughout its existence, with lead guitarist Woody Weatherman as the sole constant member. Weatherman, founding bassist Mike Dean, founding drummer Reed Mullin and vocalist/rhythm guitarist Pepper Keenan are widely regarded as its "classic" lineup. After a hiatus in 2006, Corrosion of Conformity returned in 2010 without Keenan, who had been busy touring and recording with Down, but announced their reunion with him in December 2014. More lineup changes have happened since then, with John Green replacing Mullin after his death in 2020 and Dean departing from the band once again in 2024.

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 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.
