I agree with Scramman on Railroad Earth. I like the two disc live set "Elko." I also recently picked up "The Steeldrivers" debut after reading about it in all places-The Wall Street Journal. They are all session players from Nashville with impeccable musicianship. The lead singer's whiskey soaked gravelly voice is not to be missed. The Steeldrivers are the most exciting band to hit the bluegrass scene in quite a while.
