Three full-length acts from three Puccini favorites, all starring the irrepressible Miss N (as in Netrebko). To greatest hits from her familiar rep (La Bohème, Tosca), she adds the icy heroine’s spine-tingling Riddle Scene from Turandot, set in a cruel China of invented myth. Her husband Yusif Eyvazov appears as the death-defying Unknown Prince, a role with which he may identify. —M.G.
