Watch Bombuj. In the third work of Wagner's epic cycle, Der Ring des Nibelungen, Siegmund's shattered sword is forged once again and kills the dragon that guards the ring. When Siegfried seizes the ring, he also receives its curse as he continues his fiery adventure of discovery and love. Filmed at Barcelona's Gran Teatre del Liceu in 2004, Harry Kupfer's stunning production, first staged in Berlin, numbers among the greatest productions of modern times and is recorded in sumptuous surround sound.
