Talk about a source abundant and pure: their father, Del, is among the most influential and successful musicians in the history of the genre. Years on the road with Dad in the Del McCoury Band honed their knife-edge chops, and encouraged the duo to imagine how traditional bluegrass could cut innovative pathways into 21st century music.
