Corrosion of Conformity (aka C.O.C.) was formed in 1981 in North Carolina. They went on indefinite hiatus in 2002, but reunited in 2004. However, Corrosion of Conformity is still active today.They started out as a punk band, which became a crossover/thrash band, and then turned into their modern sound, blending heavy metal with Southern rock and blues. https://corrosion-of-conformity.bandcamp.com/
