Bad Brains are an American band formed in Washington, D.C., in 1976. They are widely regarded as pioneers of hardcore punk, though the band's members have objected to the use of 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. Rolling Stone magazine called them "the mother of all black hard-rock bands", and they have been cited as a seminal influence to numerous other subgenres in addition to hardcore punk, including various subgenres of heavy metal, such as thrash/speed metal, alternative metal, and funk metal. Bad Brains are followers of the Rastafari movement.

Hardcore punk is a punk rock music genre and subculture that originated in the late 1970s. It is generally faster, harder, and more aggressive than other forms of punk rock. Its roots can be traced to earlier punk scenes in San Francisco and Southern California which arose as a reaction against the still predominant hippie cultural climate of the time. It was also inspired by Washington, D.C., and New York punk rock and early proto-punk. Hardcore punk generally disavows commercialism, the established music industry and "anything similar to the characteristics of mainstream rock" and often addresses social and political topics with "confrontational, politically charged lyrics".
