About the Show
Bluegrass Underground is a musical adventure series that shines a light on purveyors of musical authenticity in a space unlike any other on (or under) Earth. Bluegrass Underground emanates from the Volcano Room, a subterranean amphitheatre 333 feet below McMinnville, Tennessee at Cumberland Caverns. The acoustic properties of the Volcano Room are singular. In fact, the room only resonates at two frequencies meaning that experiencing live music there is akin to attending a concert inside a recording studio.
Audio engineers are amazed at the natural acoustics and world renowned lightning artist Allen Branton uses the space to paint light upon the primordial darkness found inside this cave. Music and light entwine in this series which celebrates the natural beauty and musical culture that is uniquely American. Discover the full spectrum of Americana and Roots music at Bluegrass Underground.
