There will be plenty of pickin’ and grinnin’ at the 2017 Bonnaroo Music and Arts Festival as actor/comedian/banjo virtuoso Ed Helms hosts the annual Bluegrass SuperJam on June 11.

This year’s lineup will be backed by the Grammy-winning Bryan Sutton Band and will include performances from Martina McBride, Aaron Lee Tasjan, Greensky Bluegrass, Mandolin Orange, River Whyless, Gaby Moreno, Baskery and Lillie Mae. Additional guests—both announced and unannounced—are expected to join the fun.

Bonnaroo will take place June 8–11 at Great Stage Park, the 700-acre farm and event space located just 60 miles south of Nashville in Manchester, Tenn.

In addition to headliners U2, Red Hot Chili Peppers and The Weeknd, the four-day festival will feature performances from a trio of country-centric performers: Luke Combs (June 8), Cam (June 11) and Margo Price (June 11).

Tickets are still on sale on the Bonnaroo website.
