Sid McCray, the original singer of legendary punk band Bad Brains, affectionately known as SidMac, has died, CoS reports. McCray led the band from 1977 to 1978, when they were still a jazz fusion outfit known as Mind Power. He’s credited with introducing his bandmates to punk rock, specifically through albums by Sex Pistols and Ramones, when the band took the name Bad Brains. McCray wrote early Bad Brains songs like 'The Regulator', but ultimately stepped aside as frontman to let his friend and guitarist H.R. take over. He was part of the Brains road crew.
