Actually, come to think of it, my cousin (who is one of those musicians) moved from Seattle to Asheville. (He was staying with me in Seattle, really just to get away from the east coast for a while.) And now he lives in NYC and tours in Europe. So.

Not that he is either Afro or Celtic, but I would say he's folk, in that acoustic-guitar-and-rough-voice story-telling-songs kind of way. This is him, if you'd like to give him a listen. He's good. Also he's my favorite cousin. Bit of a hipster, but a good guy overall.
