Annie Baker is a youngish playwright whose work focuses on the byways and mores of rural New England. Probably her most well-known play is Circle Mirror Transformation, an ensemble piece about a small group of people who are taking a six-week theatre workshop at the community center in a Vermont town. When I first read about this play, I immediately thought that New Village Arts in Carlsbad was the perfect local company to stage it. My wish has come true: NVA has mounted a bang-up San Diego premiere that runs through March 2.
