Thirty years ago, Pete Townshend attempted to define rock and roll to an interviewer:
“If it screams for truth rather than help, if it commits itself with a courage it can’t be sure it really has, if it stands up and admits something is wrong but doesn’t insist on blood, then it’s rock ‘n’ roll. We shed our own blood. We don’t need to shed anyone else’s.”
Too bad rap never got the message.
