I've been listening to a fair bit of Eric Clapton/Cream/Derek and the Dominos lately, and really enjoying some of the more bluesy tracks, so I thought I might like to check out some of the blues artists who influenced these guys, especially Clapton's guitar style. I read Clapton's autobiography recently where he mentioned a lot of the blues artists who influenced him, but unfortunately the book was from the library so I don't have that motherfucker handy. I remember him mentioning dudes like B B King and Howlin' Wolf though.

Anybody here well versed in blues music? What do I need to hear?
