The Greenway turns Dewey Square into an open-air dance floor beneath The Midnight Ride mural, with two DJs spinning house, EDM and techno until 10:30 p.m. Local food trucks, a Night Shift beer garden (last call 9:30 p.m.), glow sticks and a glow-in-the-dark face paint station round out the night. Free to attend; RSVP encouraged.
