If you are a guitarist, these are the guys (as one friend put it) that I can only go see once a year, because they demoralize me so much.
Trace Bundy, a.k.a. the acoustic ninja. Just found his site today and am thinking about ordering the double cd. It's that impressive - check out his arrangement of canon in D by Pachabel.
Michael Kelsey, Lafayette, IN hometown boy. He's making his way now, but still comes around every now and then. Agressive acoustic guitar stuff. And probably the best showman I've ever seen; it's almost ridiculous how much fun he has on stage.
I think they both have some video on their site. It's worth the download time, even for the dial-ups among us.
