My list will suck because I like acoustic guitar played in the classical sense, and don't have a large collection of guitar-centric music. I can really only think of a few noteworthy ones.
But, in no particular order.
Michael Hedges. One of the greats.
Michael Gulezian. What a wonderful fellow. Simply awe-inspiring when playing solo in a small coffee house. I've never heard anyone else make a guitar sing like he can.
Ottmar Liebert. Flamenco & spanish style guitar.
Ninja Edit: Oh, I have always thought that Lenny Kravitz played a pretty mean guitar too.
