There are too many great ones to list, but. I've always loved Frank Zappa's musicianship, this is an instrumental , Zoot Allures featuring mr Zappa's guitar playing, but could that band play? It takes about 1.30 to get going but it's one of the better live versions available! Listen to that controlled feedback and the other members of the band, great musicians.
Then there's Jeff Beck, I've never heard anyone who can do harmonics and whammy bar like this guy can, this song is awesome, I don't know how he does it!
There are loads of others!
Lots of great choices above too!
Cheers
