On New Year's Eve, the Met Opera premiered a new "Tosca"  in a bid for redemption following a controversial 2009 production of this Puccini classic; director Sir David McVicar and designer John Macfarlane deliver beauty and grandeur, and singers Sonya Yoncheva and Vittorio Gregorio are energetic and radiant. This is a must see for the opera fan or those interested in the form.
