Bad Brains is an American hardcore punk band formed in Washington DC in 1977. They are widely regarded as among the pioneers of hardcore punk, though the band's members objected to this term to describe their music. They are also an adept reggae band, while later recordings featured elements of other genres like funk, heavy metal, hip hop and soul. Bad Brains are followers of the Rastafari movement.

Originally formed as a jazz fusion ensemble under the name Mind Power, Bad Brains developed a very fast and intense punk rock sound which came to be labeled "hardcore", and was often played faster and more emphatically than the music of many of their peers. The unique factor of the band's music was the fact that they played more complex rhythms than other hardcore punk bands, also adapting non-punk style guitar riffs and solos into their songs.
