Pigs Eye Landing is also fun, They're out of the Upper Midwest (I guess that the band name comes from the old name for St Paul Minnisota) I'll second Great Bear Trio, also Atlantic Crossing is a band from my neck of the woods Northeastern US I get to dance to 'em Saturday. Also, had a chance to dance to Rodney Miller twice in the past month.

If it's the music you are after, the Portland Collection is a good source book of tunes, with notes on how they are used in dances, and I have heard that there's a companion recording, and a second edition.
