Tchaikovsky: Iolanta / Bartók: Bluebeard's Castle: Valery Gergiev conducts Mariusz Trelinski’s thrilling new production of these rarely heard one-act operas. Anna Netrebko stars as the blind princess of the title in Tchaikovsky’s lyrical work, opposite Piotr Beczala as Vaudémont, the man who wins her love—and wakes her desire to be able to see. Nadja Michael and Mikhail Petrenko are Judith and Bluebeard in Bartók’s gripping psychological thriller about a woman discovering her new husband’s murderous past.
