I can't resist a thread like this. One of the best I ever heard was Jens Kruger of the Kruger Brothers. This is a blugrass-ish act from Switzerland that has found enthusiastic audiences in America. Jens can give you fast and crisp bluegrass banjo, very fluent clawhammer and bursts of classical music thrown in with a sense of humor. Don't miss him if you get the chance. Otherwise, depnding on the type of banjo I'm in the mood for, I especially like Grandpa Jones, J. D. Crowe, Uncle Dave Macon, Frank Lee (formerly of the Freight Hoppers), Leroy Troy and Tommy Jarrell. Although I don't usually follow what he's up to, I know no more dextrous banjo player than Bela Fleck.
