The third opera in Richard Wagner's epic Ring cycle, Siegfried follows the adventures of the son of demigods Siegmund and Sieglinde as he conquers his enemies and rescues the beauteous Brunnhilde with the help of his magic sword. This video preserves the controversial 1976 Bayreuth Centenary production, with Pierre Boulez leading the Bayreuth Festival Orchestra. Manfred Jung leads the cast as Siegfried, with Gwyneth Jones as Brunnhilde, Donald McIntyre as the Wanderer, and Hermann Becht as Alberich.
