If you’re like us you noticed that three of the top hometown bands weren’t headlining any Art-a-Whirl lineups this year. That’s because laser-sharp Products, “post-everything” Scrunchies, and intergalactic rockers The Cult of Percolation will fill up the massive Franconia sculpture park all afternoon with their loud and proud sounds. Along with the walkthrough there’s also food trucks, bring a lawn chair. SAT, 2-6 PM. Free.
