The enduring L.A. punk band Social Distortion has overcome numerous personnel shifts, the demise of the Los Angeles hardcore scene that spawned them, and the heroin addiction of singer/guitarist/bandleader Mike Ness to achieve a measure mainstream acceptance for their rootsy, hard-hitting punk without compromise. Inspired by the fertile L.A. punk scene, Ness formed the group in 1978 with drummer Casey Royer and brothers Frank (bass) and Rikk Agnew (guitar).
