Old Crow Medicine Show

The young men of Old Crow Medicine Show scored a minor hit in 2004 with "Wagon Wheel," a reworked Bob Dylan outtake that easily ranks among the best country songs of the '00s. With its wistful fiddle line, soaring harmonies and timeless refrain, the song easily established OCMS as one of the best string bands working today, a welcome antidote to the easy-listening new grass of the Alison Krauss set and perhaps the best thing to happen to bluegrass festivals since Steve Earle took up with the Del McCoury Band. The group's newest album, Big Iron World, builds on their early success, bringing co-producer David Rawlings and Gillian Welch (on drums, no less) along for a ride through the backroads of American song. And if you're longing to hear fiddle and banjo bounce off the brick walls of the Gypsy Tea Room one last time, it's a ride you'd better catch.
