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.
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. Founder Joe Keithley is also the founder of Sudden Death Records which has released music by D.O.A. and several other bands including Pointed Sticks and Young Canadians.
