Roots of Ringworm

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.

Exodus is an American thrash metal band formed in 1979 in Richmond, California. Their current lineup consists of guitarists Gary Holt and Lee Altus, bassist Jack Gibson, drummer Tom Hunting and lead vocalist Rob Dukes. Notable former members of the band include vocalists Paul Baloff and Steve "Zetro" Souza, drummers John Tempesta and Paul Bostaph, and founding guitarist Kirk Hammett who later joined fellow Bay Area thrash metal band Metallica. There are no original members left in Exodus other than Hunting, who had departed from the band twice, in 1989 and 2004, but rejoined in 2007. Holt, who has been in the band since 1981, is the only member to appear on every Exodus album. Much of the band's career has been affected by lineup changes, feuds between both band members and record companies, two extended hiatuses, deaths of former band members, and drug addictions.

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.
