There are many "triumph from tragedy" stories in rock, but the one the probably changed the game the most was Tony Iommi's
Losing the tips of his middle and ring finger in a freak factory accident, Iommi was forced to completely change the way he played, and in the process became a heavy metal pioneer.
He played dark...
He sounded sinister...
He was, and is, one of the baddest guitarists in rock.
Never before have we ever been so thankful for a factory accident.
