Cirque-ular motion. South Sounders, here’s your chance to see Cirque du Soleil closer to home! (Cirque was at Marymoor Park in Redmond through last July.) Touring production Alegría (“happiness”) hits the Tacoma Dome this month with the company’s usual I-can’t-believe-they-just-did-that aerial, contortionist and tumbling tricks. Tickets are $28–$95; order by visiting Cirque du Soleil or by calling 800-968-2737. Sept. 15–19: Wednesday, Thursday 7:30 p.m.; Friday, Saturday 3:30 p.m., 7:30 p.m.; Sunday 1 p.m., 5 p.m.
Lunar landing. You may remember Lullaby Moon, the yearlong theatrical production that took place in Seattle parks each new moon from October 2008–October 2009. The show is back for one performance only on Sept. 10 at Gasworks Park and includes the same dozens of performers, large-scale set pieces, classical dance and music, and intriguing costumes. Wear white, and bring sleeping bags or blankets to keep warm for this unique performance. Free. 7 p.m. lucianeare.org
