For the first time ever, Massenet’s sumptuous take on the Cinderella story comes to the Met, with DiDonato starring in the title role. She is paired with mezzo-soprano Alice Coote in the trouser role of Prince Charming, Kathleen Kim as the Fairy Godmother, and Stephanie Blythe as the imperious Madame de la Haltière. Bertrand de Billy conducts Laurent Pelly’s imaginative storybook production.
