Yep.This right here is the one I thought of immediately. In my opinion, this has got to be the greatest guitar solo of all time, and to not play it note for note, at the exact tempo is an absolute injustice.
Really, damn near everything Gilmour has done. He's such a tasteful musician, all of his solos are composed and perfect for the piece they accompany.
He's one of my favorite guitarists, no shreddy wanking, just tasteful badassery. Lots of lessons there for the wankers who think fretboard gymnastics is musicality.
