With one leg in the world of modern dance and one leg in the world of burlesque and some weird third leg in the world of performance art, Cherdonna and Lou straddle a variety of genres like no one else. In a bittersweet twist, the duo’s brand-new show, My Obviously Unsuccessful Lifestyle, is their collaborative swan song before venturing off on solo paths. No fan of dance, burlesque, or drag should miss it. (Velocity Dance Center, 1621 12th Ave, brownpapertickets.com, 8 and 10 pm, $18 adv/$20 DOS, July 13–14)
