Lots of people have been asking this question, and the answer definitely is Robert Randolph. If you seriously haven't checked out their rock 'n' blues jams, please do. I just picked up his Live At The Wetlands disc and he does six epic tracks in 70 minutes. It's high-quality bluesy rock.

I'm gonna say it now, just in case anybody else hasn't: If John Belushi and Dan Akyroyd had made The Blues Brothers in 2005, it would have included a scene with Robert Randolph & The Family Band doing a tune. And speaking of that hilarious movie, feel free to put it under my Christmas tree or yours by getting the 25th Anniversary Edition.
