Toy Boat Community Art Space celebrates its first anniversary with a sock-hop spectacular. Both sock hop and spectacular are accompanied by a bunch of exclamation points on the show poster — keep that in mind when planning an outfit and polishing your moves for the themed dance (!). Little Diddy Know and Shangri Las provide live music; Forty Fingers & A Missing Tooth and Runaway Circus offer up sideshow entertainment. Saturday, July 27 at 8 p.m. Free. http://www.toyboatcommunityartspace.com.
