(Un ballo in maschera)
The second in BBC2's season of Verdi operas. Tonight starring conducted by Claudio Abbado
When the King of Sweden met his death at the hands of conspirators during a masked ball in 1792, the motive for the crime was certainly not any affair between the king and his secretary's wife.
However EUGÈNE SCRIBE'S rewriting of history inspired one of Verdi's most radiant love duets. With this production Claudio Abbado launches his musical directorship of the Vienna State Opera. Act I
Scene 1: The royal palace in Stockholm
Scene 2: Ulrica's dwelling
