Anders, my recommendation would be Dwight Diller. I'm listening to his "Just Banjo '99" and it is about the best clawhammer I've ever heard, all solo so you really can hear every note (whether you can play them or not, I don't know, but he's got an instructional video coming out in the fall). If your local store doesn't carry any of his stuff, you can eMail him at dillerwva@neumedia.net. He also has an online site with a discography (which doesn't yet include the one I'm listening to):
