Erin Markey's surprising, left-field humor pervades Singlet, which explores the edges of the sexual attraction within friendships. The play features two actors, Markey and Emily Davis, who seamlessly transition between several different characters as they break and rebuild the boundaries of their constantly shifting relationship. The show opens up with Davis and Markey nose-to-nose. Together they trying to reach "the holy grail of clothes," as Markey described it, which is fitting into an extra-small shirt. The campy critique of feminine expectations is hilarious, casually and cleverly revealing the characters' deep psychological issues even as they skim along the surface of their relationship. In the next scene, the two play coaches co-teaching a social studies class. That dynamic morphs into a kinky role play scene between a coach and student, which then morphs into even stranger and more intimate relations. Markey's impossible-to-categorize, genre-bending work is the perfect inaugural piece for WET's new GUSH series. Samie Spring Detzer, WET's artistic director, envisions the new slot as a way to inject some cutting-edge, experimental, contemporary theater into Seattle's scene. by Rich Smith
