Bluegrass Underground

The bluegrass band 18 South kicks off the performance series, which is taped in Cumberland Caverns in McMinnville, Tenn.

From multiple Grammy wins to The Hunger Games' soundtrack, 2012 is a breakout year for The Civil Wars. Intricately woven phrasing and airtight harmonies mark the minimalist duo's powerfully ballads and astonishingly frank songs on the paradoxical nature of love.

Season 3 kicks off with Old Crow Medicine Show.

The Season 4 premiere features the successful jamband Widespread Panic who meld southern rock, blues-rock, funk and hard rock in a stellar performance.

Leftover Salmon perform in the Season 5 premiere.

Savor the Underground debut of a group that personifies “Americana”: Guitarist-singer-songwriter Rawlings with Gillian Welch, Punch Brothers bassist Paul Kowert, fiddler Brittany Haas and former Old Crow Medicine Show guitarist Willie Watson.

Enjoy the irresistible Cuban groove of the genre-leaping Grammy-winners fronted by the transcendent vocals of Raul Malo. The band has won awards from the Academy of Country Music, the Country Music Association and the Americana Music Association.

Season 8 moves to a new location 40 miles south of the previous site, The Caverns at the foot of Monteagle Mountain in the hills of Grundy County, Tennessee near Pelham, Tennessee.

Truly iconic, profoundly influential, and a catalyst for an entire movement in country rock and American roots music, the Nitty Gritty Dirt Band, continues to add to their legendary status. With multi-platinum and gold records, strings of Top 10 hits, multiple Grammy, IBMA, CMA Awards, the band's accolades continue to accumulate.

This season, due to the COVID-19 pandemic, each episode offers previous performances from two or more artists who have graced the underground stage over past seasons.
