Last year, the burlesque contingent of the Moisture Festival (the annual varietè revel) busted out of Fremont and sold out houses in ACT's more intimate theater. Last year's stars—the Aerialistas, Trixie Little and the Evil Hate Monkey, Chica Boom—are back, joined by a dozen more of this town's best showgirls and boys. The unpredictable mix is what every burlesque cabaret should aspire to: ribald humor, whimsical striptease, sexy surrealism, and clever physical theater delivered in delicious little bites. (ACT Theater, 700 Union St, 7:30 and 10:30 pm, $22, 18+. Through Sun April 6.)
