This past weekend, our friends at the Bowen McCauley Dance Company in Arlington hit the Arlington County Central Library with a flash mob to help promote Wolf Trap's upcoming run of MAMMA MIA! We've got a snippet of the amazingly choreographed mob in video for you below. Dozens of lucky Arlington County Central Library patrons were treated to this four minute performance, which featured two of the Bowen McCauley's principal dancers. Not your average library fare. Hope to see you here Thursday through Sunday for one of the production's seven performances.
