Which stuff did you hear? i know that Peter has done some recent stuff...not heard it, so I cannot comment on it except to say that reviews I have read have not been so favorable. Have you heard the early Fleetwood Mac stuff from the sixties? The album names escape me but that is the stuff to try. If you still think he is a poor Clapton wannabe, well, to each his own, but my tastes run the exact opposite. I think Green's best stuff is the real thing and that Clapton is the blues-wannabe.
John Mayall - A Hard Road: The early tunes show that Pete had problems playing in tune. He gets a bit more interesting later on the disc. Still, he's walking in Clapton's shoes.
Fleetwood Mac - Then Play On: Makes me wonder what the big deal is.
Fleetwood Mac - Live in Boston, V1 & 2: who's who?
Also one of the Splinter Group discs. So forgettable I don't even know what I did with it.
