There is much to say about the Met's new production of Le Nozze di Figaro, which opened last night. So many impressive aspects, including Sara Erde's compelling choreography, Jimmy Levine in fine form, and much wonderful singing. But what stood out above all was Marlis Petersen's Susanna—I have never seen better. She is the complete package—the perfect voice, a profound connection with her character, irresistibly flirtatious. Somewhere Mozart is smiling.
