Sierra Hull has been recognized from age 11 as a virtuoso mandolin player. She's played the White House, Carnegie Hall and the Kennedy Center, and became the first bluegrass musician to receive a Presidential Scholarship at the Berklee College of Music. Noam Pikelny has emerged as the preeminent banjoist of his generation. He is a founding member of The Punch Brothers, and a three-time Grammy nominee. If that isn't enough, they're joined by Stuart Duncan, considered by many to be bluegrass's top fiddler. He has chalked up a career that includes four Grammys, a slew of Academy of Country Music awards, and nine titles as the International Bluegrass Music Association's "Fiddler of the Year."
