Two young people’s search for self-identity and their meeting at the end of this opera are the hopeful elements in a story which moves irremissibly towards disaster. What was to be Wagner’s humorous contrast to the Twilight of the Gods evolves to become the most introspective title of the saga, where solitude and nature become prominent, and where even the proud god Wotan shows his most vulnerable side. Completed in 1871, it premiered in 1876, six years after the preceding opera, The Valkyrie. Siegfried marks a qualitative advance with respect to orchestral continuity and symphonic technique, achieving scenes such as the Forging of the sword Nothung, the Forest Murmurs and the Awakening of Brünnhilde, among its most memorable moments. The production by Canadian Robert Carsen was first seen in 2007 at the Cologne Opera, and invites us to a passionate vision where nature is the true protagonist, submerging us in an ugly and polluted world where the characters wander, groping in the darkness of their hopes and ambitions.
