Opera Atelier’s remount of Mozart’s The Marriage of Figaro opened last night at the Elgin. It’s a curious production made up of parts that don’t really fit together, hence the review title. At the core is a rather elegant traditional production. It’s wigs and crinolines and might have been seen almost anywhere almost any time in the last fifty years or so. Most of the excessive baroque gesturing is gone and the acting is stagey but no more so than in many opera productions.
