19. Bad Brains, 'Bad Brains' (1982)
The African-American Rastas in Bad Brains had roots in jazz and reggae, yet they helped found the D.C. hardcore scene with their self-proclaimed "P.M.A." — positive mental attitude. Named after a Ramones song, they were already local legends by the time they dropped their 1982 cassette-only debut, with its terrifyingly fast thrash-dervish attack "Pay to Cum."
