Have a great night in the cave with the atomic-powered string band Old Crow Medicine Show.

Few bands in recent memory have done as much to bring new audiences and young fans to bluegrass/old-time music as the atomic-powered string band OCMS. But frontman Ketch Secor’s fine original songs, including the gold-certified hit “Wagon Wheel,” and the band’s solid musical chops please more traditional fans, as well. Add in a stage show equivalent of a moonshine-Red Bull highball and you have the makings of a great night in the cave and one incendiary half-hour of television.
