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.

This 1-hour specially curated presentation highlights the multiple musical genres that this series explores including Country, Gospel, Jazz, Americana, Folk, Indie, Rock ‘n’ Roll and yes … even Bluegrass! Hence, the series’ slogan, “A little bit Bluegrass, a little bit Underground!”

The special program treats viewers to 11 performances from the cave with Grammy award-winning artists as well as electrifying emerging artists who made their national television debut here on Bluegrass Underground via PBS.
