Santana's probably the most famous guitar player in the Jazz-rock idiom yet for me AL Di Meola, John Mclaughlin and Shaun Baxter kick his ass musically and technically (they play flamenco style acoustic stuff with Paco-de Lucia, God are they a talented trio). His stuff sounds a bit samey to me, I've never understood the big deal, just like with Clapton. Just cause these guys play slow stuff with bends and vibratos people think they're great guitar players but I've heard it all before. If i want soulful stuff I'd rather listen to Dave Gilmour (particularly on Pink Floyd's Division bell) or Alex Lifeson (from Rush, he can also shred like a maniac). I like the way Alex can play slow stuff with volume swells and pinch harmonics, that's so damn hard.
