The Zac Brown Band wrapped up the inaugural Nashville edition of its Southern Ground Music & Food Festival this weekend with an all-star lineup of special guests. Dwight Yoakam, Gregg Allman, Sheryl Crow and John Mayer all took the stage with Zac, playing their own hits with the help of the host’s versatile seven-piece band. Dwight offered “Fast as You” and “Guitars, Cadillacs,” Sheryl Crow turned in “Every Day Is a Winding Road,” and  Gregg Allman stormed through the bluesy Allman Brothers classic “One Way Out,” while guitar wiz John Mayer offered inspired solos throughout the evening. Zac will be doing it all again—with a different roster of special guests, including Charlie Daniels and Grace Potter—Oct. 20-21 in Charleston, S.C. Last year's Festival in Charleston was a true religious experience for me. If you have any vacation time left this year, you won't go wrong with a trip to the coast for this show.
