This annual family bash on the Rock Hall's plaza will feature music, activities and more than a dozen community partners. There will be balloon twisters, chalk murals and bubbles. Local musician Jesse Jukebox will present an interactive concert, meaning he'll bring his arsenal of tambourines, shakers, kazoos and all sorts of instruments. He'll also be bringing Wally, his monkey puppet that all the kids love, and will play original music from his four albums, as well as covers from favorites of the parents, like Lizzo, Taylor Swift and They Might Be Giants. Admission is free.
