Bad Brains—or “The Bad Brains,” if you want to be completely accurate—were one of the very first American hardcore punk bands with a history that dates back to 1977 in Washington DC. They evolved out of a jazz fusion group but later got harder and faster and more strident with their lyrics. And by incorporating everything from funk to soul to reggae into their sound, they showed young punks what was possible with this new music. A young Dave Grohl was a big, big fan. This was their debut single from February 1980.
