One of the city’s finest actors, Peter Vann got serious in the directing game this year. His staging of the complex musical Caroline, or Change for Street Theatre Company was a major accomplishment, bringing together diverse community players to tackle the subject of race and society in America. Vann also made his Tennessee Repertory Theatre directorial debut with an effectively brooding production of Dr. Jekyll and Mr. Hyde, following up that effort with a delightfully re-energized version of Go, Dog. Go! for Nashville Children's Theatre.
