Bluegrass is cool again.  Wait, when was it cool in the first place?  I'm sure there was a time when everyone in town would gather together at the barn hoedown and Ma and Pa would take a spin on the dance floor.  Well, this one by Alison Krauss and Union Station puts you there.  It's a mix between traditional and an edge-off twang of new grass softness.  It's the work that really heralded in Alison Krauss and her crew and dare I say laid a precursor for the popular runaway success of "O Brother Where Art Thou?" soundtrack and to a lesser extent the Dixie Chicks.
