Deliverance

Leaving their hardcore and thrash past behind them, Corrosion of Conformity embraced their southern roots (and their love of Black Sabbath) on their fourth album and found a full-on stoner groove. New vocalist Pepper Keenan’s laconic singing lent itself to this new direction, but despite the change in sound they retained their animosity — unexpected radio hits “Albatross” and “Clean My Wounds” delivered some pretty harsh mellows.
