Some of Steve Vai's stuff should qualify and Satriani is a no-brainer. I've also got a weakness for anything that Stevie Ray Vaugh put out ("Supersticion" or "Mary Had a Little Lamb" ring a bell?) Those are fairly modern, though.
Early Clapton (Layla comes to mind), Zepplin (Whole Lotta Love), Aerosmith (Walk This Way), Hendrix (Voodoo Child), Frampton, Queen (yes, Brian May is a kick-ass guitarist), Ted Nugent, Santana (especially "Black Magic Woman"), etc., etc...
