While the cancellation of Gregg Allman’s headlining set was an unfortunate loss, the Peach Music Festival has done a great job putting the pieces together for the holes in their lineup. The festival still put The String Cheese Incident members with the Allman Brothers Band family for a collaborative set, had Gov’t Mule extend their Sunday night set and booked Rich Robinson Band to perform as well. Today, they’ve outdone themselves, announcing the formation of a new trio: Russo, Benevento & Burbridge.The group will certainly be an offshoot of the famed Benevento Russo Duo, making their debut as a trio for the first time this Sunday at the Peach. The RB&B supergroup is sure to dominate their festival set, and who knows what special guests might find their way into the jam.While we send our healing thoughts and prayers to Gregg Allman, it’s certainly worth praising Peach Fest for their quick turnaround on the new lineup additions. The festival kicked off last night as well, with sets from groups like Dark Star Orchestra, Electron (Pink Floyd set), Dopapod and more!Speaking of Joe Russo and Oteil Burbridge – have you seen the Brooklyn Comes Alive lineup yet?
