Pink Floyd obviously has well known solos, but this is one of my favorites. High Hopes
The solo comes in at 5:05. Gilmour is just tasteful, one of very few that really know how to let the notes sing.
Another one would be Since I've Been Loving You from Led Zeppelin LINK
. It's really raw. You hear some mistakes in it, but the dude is playing out of his mind and just feeling it.
This entire video is incredible. And out of all of the Stevie Ray Vaughan songs, I think this is probably my favorite. Tin Pan Alley - Stevie Ray Vaughan LINK
This is damn near perfect.
Another would be Dire Straits Down To The Waterline
. Not a big solo, but really well executed. The entire guitar work in this song is fricking sick.
