Well, we all started somewhere, that's why we have the great memories we have about music, it's always better to let them explore on their own, remember the first time you heard xxxxx? And the smell you had around you, the car you heard it in? Things like that last a lifetime, and make us who we are, put smiles on our faces when we're old.
On the same token, I remember my Dad bringing home 'Dreamboat Annie I was in hog heaven, that voice, those drums......that sound on our crappy little SX-something (35watter from the mid 70's). So get him some stuff, then let him find what he wants......
