Willie Nelson & Family, Grace Potter and the Nocturnals, Edward Sharpe and the Magnetic Zeros and others will join Zac Brown Band at their Southern Ground Music & Food Festival.
The Nashville, TN edition of Brown’s bi-annual festival will take place at The Lawn at Riverfront Park on Friday and Saturday, September 27 and 28. Other acts slated to appear include: Eli Young Band, Kacey Musgraves, The Head and the Heart, and Trombone Shorty & Orleans Avenue.

Continuing the festival’s annual tradition—which the band kicked off last year with iconic artists such as Gregg Allman, Sheryl Crow and John Mayer—ZBB’s “Super Sets” will close both nights with special sit-in performances by Kenny Chesney, John Fogerty, Jason Mraz and others.

Additional acts will be confirmed in the coming weeks. Zac Brown Band are expected to confirm the Charleston, SC edition of Southern Ground in the near future.
