Cosi fan tutte. Mozart's romantic comedy about a cruel, fidelity-testing charade has a starry new recording led by the Philadelphia Orchestra's Yannick Nézet-Séguin with the Chamber Orchestra of Europe and singers including Miah Persson and Rolando Villazon. This intelligent and alert, if not classic, performance comes in a handsome three-CD box. Deutsche Grammophon. To buy: $35.93, at Amazon.com.
