One of the founders of America's jam band movement, Yonder Mountain String Band blends bluegrass, rock and countless other influences, pioneering a sound of their own. A traditional bluegrass band at first glance, YMSB created music that is genre-transcendent and attracted a large and fiercely loyal following. The Colorado-based foursome has toured over the past 11 years, playing clubs and major festivals, even opening for Barack Obama in Denver at Mile High Stadium.
