Zac Brown Band brought their Southern Ground Music & Food Festival to Charleston, SC over the weekend and were joined by several special guests throughout the weekend including Derek Trucks, Susan Tedeschi, Sam Bush, Michael Franti and others over the course of their two sets.

The sit-ins started on the first night as ZBB welcomed out Michael Franti and Sam Bush for a cover of Bob Marley’s “No Woman No Cry” before Bush joined in on Jimmy Martin’s “Freeborn Man” later on during an acoustic portion of the show. Longtime collaborator with the band Doland Dunleavy joined in for the encore to bolster the guitar attack for “Heavy is the Head” that the group originally recorded with Chris Cornell.

On the second night, ZBB started out with Kacey Musgraves, who added to covers of “Hey Good Lookin’” as well as “Devil Went Down to Georgia.” Susan Tedeschi and Derek Trucks then flanked the band for a cover of the Beatles’ “I’ve Got a Feeling” featuring Tedeschi on lead vocals. Watch below.

Also included on the second night were sit ins from Hunter Hayes, who came out for the band’s original “Keep Me in Mind” before Dunleavy once again joined the group for “I Play the Road” and the finale of “Enter Sandman” before the band departed for the encore.
