Hendrix...Child of alcoholic, and abusive parents. Junkie, herion addict, overdosed on pills and choked on his own vomit. No significant relationships, no claimed children. Dead at 28.
Talented, yes. "Baddest man". not even on the list.
But if we limit to "baddest musician" whatever that means (perhaps most influential), I vote for Beethoven followed by Bach. Rock is only a very small part of the overall evolution of music.
