In addition to headliners including Megan Thee Stallion, Chance the Rapper, Green Day, Weezer, Guns N' Roses and Miley Cyrus, 88Nine Radio Milwaukee favorites Run the Jewels, Yola, Black Pumas, Future Islands and The Flaming Lips are just some of the acts playing the festival's side stages. The more you comb through the schedule, the more gems you'll find.
