A newly reunited Ween were among the performers at this year’s Bonnaroo Music and Arts Festival, which took place last weekend in Manchester, Tennessee. After their show, they retired to their dressing room, where the band’s Mickey Melchiondo, Jr. (aka Dean Ween) had a jam session with Josh Tillman (aka Father John Misty), who also performed at Bonnaroo. Ween plays bass and FJM joins him on the drums. (Tillman previously played drums in Fleet Foxes before taking on the Father John Misty moniker.) Also present was Kurt Vile, who played Bonnaroo with his band the Violators. He stands and watches Ween and FJM jam while a pair of fans who snuck backstage and into the dressing room sit on the couch. Watch it happen below.
