Eliot Fisk is the best classical guitarist I am aware of. As mentioned about the Paganini Caprice No. 5 used in the "Crossroads" movie, Fisk does not only the entire 5th caprice on solo guitar ... he does the entire series of 24 caprices.

You can hear Caprice No. 5 on that page. Fisk is so good it's astonishing.

On electric guitar, very few people will ever approach the level of Shawn Lane. Search YouTube.com or google him. Unbelievable technique.
