Robert Lepage’s landmark staging of Wagner’s Der Ring des Nibelungen, unveiled over the course of the 2010–11 and 2011–12 seasons, was the first new Met production of the complete cycle in more than 20 years. Combining state-of-the-art technology with traditional storytelling, it brings Wagner’s vision into the 21st century. With Die Walküre, the story of the Ring enters the world of human beings. Jonas Kaufmann and Eva-Maria Westbroek are Siegmund and Sieglinde, the twin children of Wotan, sung by Bryn Terfel. Deborah Voigt stars in the title role of the Valkyrie Brünnhilde, Wotan’s favorite daughter. James Levine conducts.
