The third annual Major Rager will return to Augusta, GA, on April 7 and will include a special performance by Umphrey’s McGee that will feature an “All Night Wrong” set made up of covers.

The event has revealed today that UM will be joined for that performance by Trey Anastasio Band members Jennifer Hartswick and Natalie Cressman, along with members of the James Brown Band.

Also on the Rager bill are The Revivalists and Earphunk, and the after party will feature the UM/TAUK collaboration TAUKing McGee. A portion of the proceeds from the event will go to benefit Turn Back the Block. Tickets are available here.
