FIRST DAY OF THE RING CYCLE. Fleeing for his life, Siegmund seeks shelter at Sieglinde's house. Her husband Hunding happens to be one of Siegmund's pursuers, and the two of them must cross swords the next day. As Siegmund laments his lack of a weapon, Sieglinde directs him to the sword Nothung stuck in an ash tree. Despite discovering they are twin siblings, the two fall in love. The King of Gods Wotan, their father, sends his Valkyrie daughter Brünnhilde to aid Siegmund. Fricka protests, and Wotan uses his spear to break Siegmund's sword during the battle. Siegmund is slain, but Brünnhilde rescues both the sword fragments and Sieglinde who is pregnant with Siegmund's child Siegfried. Wotan is angry that she intervened, but since Brünnhilde is his favorite child, he merely strips her of immortality and sends her into an enchanted sleep, surrounded by fire. This modern Kupfer/Barenboim production was performed between 1988 and 1992 to rapturous reviews in the international press.
