Dynamic cities have always produced vibrancy, but it doesn’t just happen. According to author Blair Ruble, it takes a plan built on a vision of community, diversity, and inclusion. And a primary vehicle for such plans is the performing arts. In his latest book, “Performing Community,” Ruble provides insight into the theoretical with real-life examples from places like Washington, DC, and Detroit, providing lessons for the cities of the future through an exploration of past and present. That’s the focus of this edition of  Wilson Center NOW.
