Dan Tyminski was six years old when his parents began taking him to fiddle contests, square dances, and bluegrass festivals across New England. For a young musician who would later become one of the biggest names in modern-day bluegrass, those early experiences were life changing. His voice famously accompanies George Clooney’s performance of the Stanley Brothers’ classic song, “I Am A Man of Constant Sorrow,” in the film, Oh Brother, Where Art Thou? and his vocal collaboration with Swedish DJ Avicii on the song “Hey Brother” was a global smash, having been streamed more than a billion times to date.
