My Morning Jacket headlined Somerset, WI’ s Somerset Amphitheatre on Friday night. Band of Horses and Trampled by Turtles shared support duties and, during MMJ’s encore, the members of Trampled by Turtles joined My Morning Jacket frontman Jim James onstage. The hometown group backed James on the MMJ number “Wonderful (The Way I Feel),” a song they covered in their hotel and posted online a few weeks ago. As the members of the group took the stage, James said he felt something “real good” and “real deep” during their opening set. My Morning Jacket will perform in Rochester, MI tomorrow while Trampled by Turtles will return to the road for a show at Winnipeg, MB on August 30.
