Roots of Down

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.
