Bela Fleck and Abigail Washburn are a husband-and-wife duo who blend virtuosic clawhammer and three-finger banjo playing into a genre-defying sound that spans Appalachian folk, bluegrass, and world music. Their album Echo In The Valley, available at Collide Records, showcases their intricate dual-banjo interplay and rich vocal harmonies, cementing their place as one of acoustic music's most inventive partnerships.
