The prologue to Wagner's giant masterpiece Der Ring des Nibelungen unfolds the beginning of an epic journey when Alberich seizes the ring of gold, its awesome power unleashing an unstoppable story of deceit, destruction, death and transfiguring love. Filmed at Barcelona's Gran Teatre del Liceu in 2004, Harry Kupfer's stunning production first staged in Berlin, and recorded in sumptuous surround sound, numbers among the greatest productions of modern times.

Since its premiere on 2 June 1937 in Zurich, Alban Berg's second opera "Lulu" has the reputation of being surrounded by scandals. On the one hand, this is due to the dubious character of the subject, the man-eating femme fatale, which Berg had taken from Frank Wedekind's two Lulu tragedies – "The Earth Spirit" and "Pandora's Box" – and combined into one opera libretto. On the other hand, Berg's widow had (for personal reasons) repeatedly refused to have the opera completed, which was unfinished when Berg died. This video is of the unfinished two-act torso of "Lulu."
