Formed in Charlottesville in 2003, the band started a journey that took them from a suburban upbringing with a pop MTV soundtrack to an all-consuming obsession with bluegrass, which, in turn, took them to the stage of the Grand Ole Opry and led to an acclaimed debut album on Rebel Records, the pioneering bluegrass imprint and longtime home of Ralph Stanley. The International Bluegrass Music Association named them emerging artists of the year in 2004. But even as they were being embraced by their peers in bluegrass, their music was shifting and extending outward in directions that could no longer be contained under the bluegrass banner.
