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 2 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.
The Video Village for BLUEGRASS UNDERGROUND is set up 1,000-feet inside the cave in the vast chamber known as the Ten Acre Room.
Blue grass Underground creator Todd Mayo saw these for years before finally “discovering” the special acoustic properties of the Volcano Room.
Visitors are dwarfed by the massive columns of the The Boneyard Room, formed by mineral-rich dripping water over millions of years.
The Largest room of the 32-mile long Cumberland Cavern system cave, the Mountain Room is 600' long, 150' wide, and 140' tall.
The Caverns offers both easy walking tours and adventures with climbing, crawling and lots of mud. Thousands of visitors each year camp inside overnight.
Like a fringe of rock icicles frozen in time, stalactites drape the ceiling of the Mountain Room.
BLUEGRASS UNDERGROUND’S official illustrator, Roger Walker, brings a whole new meaning to “cave art” with a new show poster for every concert.
One of 10,000 caves in Tennessee, the Cumberland Caverns is best know for its large rooms and abundance of magnificent formations.
Created over 3.5 million years, The Mountain King Room is an almost unimaginable journey through space, form and time.
This formation is so named for the enormous stalagmites likes to game board pieces.
On BLUEGRASS UNDERGROUND concert days the Volcano Room fills with up to 700 guests enjoying the show in 58°F “weather,” 333-feet beneath the surface.
