OFF! are an American hardcore supergroup. The band was formed in Los Angeles, California in late 2009 by Circle Jerks/Black Flag singer Keith Morris, Burning Brides frontman Dimitri Coats, Redd Kross bassist Steven Shane McDonald, and Rocket from the Crypt/Hot Snakes drummer Mario Rubalcaba. The idea to form the band came after Coats had worked as producer on a Circle Jerks album which fell apart.
