A buttoned-up musicologist (the beautifully robust McTeer) discovers the unacademic joys of bluegrass in turn-of-the-century Appalachia. The landscape — lush and green, mountains cloaked in heavy mist — is magnificent, and so is she. But the real star is the music, which rightly delivers the emotional heft of the film. The soundtrack is blessed by country greats like Emmylou Harris, Taj Mahal, and Iris DeMent, who steal the show and sing it back in style.
