About

Bluegrass Underground is a radio show recorded live 333 feet below ground at Cumberland Caverns in McMinnville, Tn inside of what was named by the first people to behold the natural amphitheatre, The Volcano Room. Here water and time entwined 3.5 million years ago to create one of the most acoustically pure natural spaces on earth. No man-made sound reaches the Volcano Room and the living rock hued amid the eons is jagged and uneven, providing limited echo.

The primordial silence and perpetual darkness give way each month to the sounds of the finest music of the greatest bluegrass musicians on earth. Regardless of outside temperature, the Volcano Room is a constant 56 degrees.

Your experience at Bluegrass Underground begins at Cumberland Caverns in the light of day. Tour guides lead you through the cave entrance and into another world.
