Erin Petty leads off the arts section with her discerning look at Artisphere, the new multipurpose resident arts center in Rosslyn that opens this weekend. Tricia Olszewski reviews two films about interrupted lives, and finds herself dismissing the new film by indie favies Ryan Fleck and Anna Boden, and digging the new romantic dramedy starring Katherine Heigl. Go figure! In theater: Chris Klimek reviews Solas Nua’s bizarro musical Improbable Frequency, Bob Mondello checks out Studio 2ndStage’s Asian-American-identity mindfuck Songs of the Dragons Flying to Heaven, and Trey Graham gets wet at Synetic Theater’s King Arthur. Ben Westhoff mounts a passionate defense of Wake Flocka Flame, a rapper who says lyrics are unimportant. And for One Track Mind, Leor Galil chats with a loud, local band with an inspired name, Shat Shorts.
