The Bluegrass Underground is a weekly radio-concert series by 650 WSM-AM, an American country radio station. The concert series is internationally acclaimed. Now they partnered with Loblolly Ventures, the company of concert promoter Todd Mayo, the tv station WCTE-DTV (PBS) and Emmy award-winning producer Todd Jarrell. They develop the concert series for national television distribution.
What makes this event interesting for us, is the location: Volcano Room at Cumberland Caverns.
