Umphrey’s McGee will team up with Widespread Panic for their September 15 show at Tuscaloosa, AL’s Amphitheater. The just-announced opening slot will come one night before the two collaborate at the previously announced Alpharetta, GA show on September 16.

The two jamband mainstays have made it a point to book a few dates together over the years, exchanging collaborations throughout both sets. Past highlights have included Jake Cinninger and Joel Cummins joining Panic for a take on “Maggot Brain” as well as John Bell fronting Umphrey’s on “Ain’t No Sunshine,” among others.
