That list also had Kurt Cobain listed at #12 -- and Kurt himself was the first to tell you he only knew 3 chords.
It was a wonky list, but then almost all of them are. Too many different constituencies unless you narrow the question. 100 most technically proficient guitarists? (could probably make a list of 100 unknown studio type muscians for that one) 100 most influential? (older guys dominate) In your case you seem to be introducing songwriting, etc.
Here's where Slash is Top 10, nay likely Top 5: Chops/Charisma. And its not just the image either, its the guitarwork itself. Not a shredder, or just a shredder, he pulls emotion out of a guitar. And that's a large part of the art. Playing notes is easy. Making them talk is not.
Joan Jett made the list of top 100 guitar players too.
I hope nobody thinks I was being an apologist for the stupid list. I am an Angus/Slash fan and I think they are both terrific bold picks for this game. I'd have taken either one (yes to play alongside McCartney who I don't think has pidgeonholed my band in any way shape or form).
Rock on! I can't wait for my #2 and #3 picks to come around. THAT is when I will decide a direction - not before.
