D.O.A. is a Canadian punk rock band from Vancouver. They are often referred to as being among the "founders" of hardcore punk, along with Black Flag, Dead Kennedys, Bad Brains, Angry Samoans, Germs, and Middle Class. Their second album Hardcore '81 was thought by many to have been the first actual reference to the second wave of the American punk sound as hardcore.
Singer/guitarist Joey "Shithead" Keithley is the only founding member to have stayed in the band throughout its entire history, with original bassist Randy Rampage returning to the band twice after his original departure. D.O.A. has often released music on Jello Biafra's Alternative Tentacles Records, and they have released an album with Biafra on vocals titled Last Scream of the Missing Neighbors.
D.O.A. is known for its outspoken political opinions and has a history of performing for many causes and benefits. Its slogan is "Talk Minus Action Equals Zero." The band's lyrics and imagery frequently advocate anti-racism, anti-globalization, freedom of speech, and environmentalism. In support of the Vancouver 5 defence fund, the band released the single Burn it Down from Hardcore '81.
