1) Vancouver's D.O.A. were an early and extremely influential punk rock band. Formed in 1978, they quickly got down to business by releasing the Disco Sucks EP on singer/guitarist Joey Shithead's own Sudden Death label. Along with other early pioneers, they blazed the trail to a North American punk scene by putting out records and touring with virtually no existing 'scene' infrastructure to rely on. Early shows included clashes with audience members and police, and they can attest that police riots at punk shows were not strictly an LA occurrence.
The original D.O.A. lineup was Joey, bassist Randy Rampage, and amazing drummer Chuck Biscuits. Their first full length came out on Friends records in 1980, and was soon followed by 1981's seminal Hardcore '81 LP. The latter is commonly sited by the first wave of "hardcore" bands as a catalyst and namesake for the that movement. Following this record both Randy Rampage and Chuck Biscuits left the band. Chuck joined Black Flag and began his long career as a punk rock band slut (Social D, Circle Jerks, Danzig). His brother Dimwit took over for him, and Wimpy from the Subhumans joined on bass. D.O.A. jumped to Jello Biafra's Alternative Tentacles label for the War on 45 EP and most of their subsequent records (short stints at Frontier and Enigma didn't last). War on 45 record found them attempting to ditch the punk straightjacket by interjecting funk, reggae, and a cover of Edwin Starr's Motown classic "War" into the mix. Apparently it actually charted in Billboard.
While D.O.A. shared the political commitment of Jello's Dead Kennedys or fellow Canadians the Subhumans, they also cultivated a party band image (exemplified by the cover of their 1985 effort, Let's Wreck the Party). Their manager Ken Lester billed them as a "populist" band. Joey has kept at it with various backing bands over the years, putting out a 1995 album on a Virgin subsidiary before revamping the Sudden Death label for a few albums and reissues.
2) D.O.A. (Disciples of Annihilation) are New York City hardcore techno / speedcore producers who helped to define the New York City hardcore/speedcore sound during the mid 1990's. They are known for their work as a group on Industrial Strength Records as well as for their many solo productions.
3) D.O.A. is a rap group from Stockton, Ca.
From Wikipedia:D.O.A. is a hardcore punk band from Vancouver, British Columbia, Canada. They are often referred to as the "founders" of hardcore punk, along with Black Flag, Bad Brains, Teen Idles and Minor Threat. 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. However, original bassist Randy Rampage has been active in the band in recent years and has played on two of the band's last three albums, although he is not in the current lineup. D.O.A. has often released music on Jello Biafra's Alternative Tentacles Records, and they have released an album with Jello Biafra titled Last Scream of the Missing Neighbors.
D.O.A. has always maintained an uncompromising anarchist populist political stance. The band 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 has been active on many issues, including Anti-racism, anti-globalization, freedom of speech, and the environment.
Founder Joe Keithley now spends a great deal of time working with his record company Sudden Death Records which has branched off into many areas of music.
