Re: Been listening to a lot of Floyd lately, and...
David Gilmour is still one of my favorite guitarists...I think he demonstrates more than anybody else that a solo can still be magnificient without being played at a hundred miles an hour. I know a lot of people aren't into the post-Waters stuff, but I think "Division Bell" has some of Gilmour's best guitar work. Just about every song on that CD, especially the latter half, are excellent.
"Dark Side of the Moon" and "Wish you were here" are also phenomenal. "The Wall" has some weird tracks, but also a lot of true timeless classics, like "Another brick in the wall part 2", and "comfortably numb." The solo in "Mother" was the first solo I ever learned. It's short and simple, but still one of my favorites.
If you want an absolutely incredible live album, pick up "Pulse." It's a good mix of the old and new.
