Comprising four separate operas, Der Ring des Nibelungen (The Ring of the Nibelung) is one of the supreme works in the history of music. Part II of the tetralogy, Die Walkure, centres on the young lovers Siegmund and Sieglinde, whose relationship angers Fricka, goddess of marriage, and on the disobedience of the Valkyrie Brunnhilde who is sent to carry out Fricka's wishes. Performed by an all-star international cast, the work features thrilling set-pieces such as Wotan's Farewell and the Ride of the Valkyries.
