Maybe music that’s, ahem, louder than life isn’t your thing. If this month’s festivals are too noisy, too pricey, or too crowded for your liking, there’ll be a free (and family-friendly) alternative at Waterfront Park, where you can dance to your choice of three music stations (Top 40, Decades, or music for kids) through wireless headphones. The Downtown CineBus, a former ambulance turned mobile projector, will provide colorful visuals. — Carolyn Brown
