Corrosion of Conformity (also known as C.O.C.) is an American heavy metal band from Raleigh, North Carolina formed in 1982. For almost the majority of its existence, the band has consisted of guitarist Woody Weatherman, bassist Mike Dean (who left in 1987 but rejoined six years later), drummer Reed Mullin (who left in 2001 but rejoined nine years later) and vocalist and rhythm guitarist Pepper Keenan (who joined the band in 1989). 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.

Corrosion of Conformity started as a hardcore punk band but later moved towards a slower and blues-tinged heavy metal sound. To date, the band has released seven studio albums, two EPs, one compilation, and one live album. Their first three studio albums―Eye for an Eye (1984), Animosity (1985) and Blind (1991)―attracted the attention of Columbia Records, who signed the band in 1993. Corrosion of Conformity found success with the release of their 1994 fourth studio album, Deliverance, which peaked at number 155 on the Billboard 200 and spawned the hits "Albatross" and "Clean My Wounds". Their 1996 follow-up Wiseblood was also successful, and became Corrosion of Conformity's highest-charting album in the United States, peaking at number 104 on the Billboard 200. Their latest album, IX, was released on July 1, 2014.
