George Harrison instantly comes to mind, but also someone who people might not think of is Eric Johnson. I say Eric because I know someone who went to the Himalaya's for a vacation and actually met Eric while he was there. He said he was there for 'spiritual fulfillment' or something along those lines and that he was doing some type of meditation. This was right before he released Venus Isle, which to me is one of his best works and really underscores his work on Ah Via Musicom.
