The Appalachia Waltz Trio, Live at NPR

Audio will be available later today.

Fiddler Mark O'Connor, violist Carol Cook, and cellist Natalie Haas make up the Appalachia Waltz Trio. The trio joins NPR's Fred Child in Studio 4A to talk about the fiddling roots of American music, and to play some old-time songs from their new CD, Crossing Bridges.
