If you really want to get away from clawhammer, three-finger, etc., listen to Rob Murch. Couldn't find any clips, but here's his CD.

On the other hand, if you want to see some great clawhammer (including a fretless Frank Proffitt banjo), try these:

Jeff Davis on fretless

Jeff Davis, Pretty Polly

Jeff Davis, Beulah Land
