Carlos Montoya - Spanish Guitar
I saw him back in the 70s at the UofA and was a forever devotee of Flamenco and Spanish Guitar music. I had heard that kind of music before, of course. But I had no idea people could make a guitar sound quite like that. And I was entranced with his fingerwork. I started practicing rolling my fingers on castanets after that - not that it had anything to do with guitar, just the finger control was amazing.
