Tracy, I'm making him the subject of my blog next week. I'm a big fan of fingerstyle players like Michael Hedges, Antoine Dufour, and Andy McKee... all of which can be found online playing similar harp guitars in the same style. None of those guitars are near as gnarly as Keith's tho... that thing is just sick!
I'm not sure what his ambitions are, but Candy Rat Records specializes in promoting players like Keith. If he's interested, he should contact them... I'm sure he would blow up on the fingerstyle scene!
