D.O.A. is a hardcore punk band from Vancouver. Their career began in 1978, and they invented the term "hardcore punk" to describe their sound. As such they are often referred to as the "legend" or the "founders" of Hardcore by their following. Singer/guitarist Joey "Shithead" Keithley is the only founding member still in the band.
D.O.A. has always maintained an uncompromising leftwing populist political stance. The band is known for its outspoken political opinions and has a history of playing for many causes and benefits. Its slogan is "TALK-ACTION=0". Anti-racism, anti-globalization, freedom of speech, and the environment are a few of the issues the band is known to rally around. Many bands cite D.O.A. as an influence, including Red Hot Chili Peppers, Green Day, Rancid, and The Offspring.
The band's first two albums, Something Better Change and Hardcore 81 are two of the top five Canadian punk rock albums of all time. Their Triumph of the Ignoroids EP used a picture of Margaret Trudeau without permission, leading to a lawsuit that resulted in its withdrawal from the market.
Vancouver Mayor Larry Campbell declared December 21st to be "D.O.A. Day" in honor of the band's 25th anniversary.
