A niche of ska/punk/hardcore. The crack rock scene sprouted up from the squats of New York, led by singer/songwriter/guitarist Ezra Kire and his many crack rock bands: Choking Victim, Leftover Crack, INDK, Morning Glory and The Crack Rock Steady 7. The message of pretty much all these bands include: Take Drugs, Drop out, Squat, Kill Cops and the Government and dont be a racist asshole.
Crack Rock is one of my favorite genres.
