There's been a bit of an identity crisis at the shabby, comfy old Fox over the past year — a handful of fantastic shows, as well as a couple that completely misfired. This summer, a new executive producer, Helen R. Murray, takes over, and her hire says a lot for Aurora's commitment to theater and the arts. An actor and writer, Murray founded The Hub in Fairfax, Virginia, a decade ago. She's a multi-award winner, known for working with playwrights and commissioning new plays. Before Murray takes the reins, however, the Fox will present Passing Strange, an exuberant and unusual musical by songwriters Stew and Heidi Rodewald that won the kind of praise you rarely hear from East Coast critics. Sounds like a fitting way to lower the curtain on the Fox's most recent act and prepare for the next.
