Not gonna read the previous 6 pages, but Duane Allman gets my vote.
The guy died at 24, I believe, and was so frickin' far ahead of his time it's scary.
Derek Trucks is the nephew of Butch Trucks-- one of the Allman Brothers Band's two main drummers over the years-- and even though Derek was born after Duane's death, it's obvious when listening to his guitar work that he was exposed to Duane's stuff from the time he was in the cradle.
Duane's phrasing was other-worldly. I've never heard anybody else who resembles him, other than Derek.
I've always been 'moved' by Duane's playing-- Anyone who's heard "In Memory of Elizabeth Reed" and "Whipping Post" on the Live at Fillmore East album will probably understand when I say there's a spiritual quality to his work. By that, I mean that his play evokes incredibly strong emotion in the listener in ways that are impossible to explain logically.
