Have you guys checked out the Benevento/Russo Duo? (In jamband land simply called The Duo.)
I saw them the other night and was very impressed. It's not actually "jam" music, though they improvise (their longest song is probably 7 minutes, not 18). It's just the two of them (keys and drums), with some machines and samples, but it's almost indie-type music, without vocals. They get a little avante/jazzy, but generally, it's just a good groove.
Not suggesting them for NYE (I think they're doing something with Mike Gordon), but I'm interested to hear what people who may have an inclination to Robert Randolph, Biscuits, Particle, etc. ,think of them.
