Pick one of the cds and put it in the player. Just explore this stuff in any way you feel like. I've never been a big fan of the original lp which seems to be a heretical position here, but it was the most boring of his electric stuff to me, too straigh ahead rock like; there is a Clapton jam in the Derek and the Dominoes box set that has a very similar groove. . . nothing special to me. But the Big Fun material, the takes of Willie Nelson, the material with Pascoal, and especially the versions of The Mask. . . I really enjoy those. Lots of material here to really explore. . . . I really personally don't think you have to go about it in one way or another.
