I’m eschewing the path of looking for rare examples of guitar-solo-containing music that might conceivably also be thought of as cool, and just chucking out a few favourites for consideration here.
First up, the best Jimmy Page solo that isn’t the solo to “Stairway”:
Next, the Kirk Hammett solo that I find most personally moving:
I think this is the best Richard Thompson solo (not counting the astounding duel with Swarb at the end of “Matty Groves”):
The best guitar solo not actually played on a guitar:
although it has been played on real guitars lots of times since that game came out.
