PBS’s series Bluegrass Underground will return this spring, as the station has announced that artists like Greensky Bluegrass, Railroad Earth, Bela Fleck + Abigail Washburn, Leftover Salmon and more will all be performing. The three day event will be held from March 27-29, in a particularly unique venue: the Volcano Room of Cumberland Caverns near McMinnville, Tennessee.

True to the series’ name, the venue is indeed 333 feet underground. Tickets will go on sale this Saturday at 10 AM Eastern, and can be found on the Bluegrass Underground website.

The full bluegrassy lineup: 

Bela Fleck & Abigail Washburn, Hot Rize, Chatham County Line and Robert Earl Keen on March 27. 

Jerry Douglas presents The Earls of Leicester, Lee Ann Womack, Amos Lee and The Quebe Sisters on March 28.

Greensky Bluegrass, Railroad Earth and Leftover Salmon on March 29th.
