You'll never hear him on the radio, but very few people in history have done more to help create the wide world of rock and roll than he has. Can you guess who we're talking about from this yearbook photo?

Let's be clear -- we're bending the rules a bit, this young man would not grow up to be an artist in the sense we usually talk about on these pages.
