Conductor Daniele Gatti, mezzo-soprano Michelle DeYoung, and the BSO celebrate the bicentennial of Wagner's birth with selections from five of the composer's operas, encompassing the themes of love, identity, and redemption that pervade his works. The program includes orchestral excerpts from Götterdämmerung (Twilight of the Gods), the final opera of Wagner's gargantuan Ring cycle; the powerful overture to Tannhäuser, one of his great early successes; Kundry's narrative ("Ich sah das Kind") from Act II of Wagner's moving final opera, Parsifal, whose title character attains spiritual transcendence as a Knight of the Holy Grail; the ethereal Prelude to Act I of Lohengrin, music embodying a vision of the Holy Grail itself; and the Prelude and Liebestod from Tristan und Isolde, a twenty-minute distillation of Wagner's four-hour paean to love.
