This Vienna State Opera production of Strauss’s opera of revenge, torment, violence and horror, is directed by Harry Kupfer as a tale of tyranny and bloodshed. His bold and terrifying concept is reiterated in Hans Schavernoch’s cavernous decor. He opens with an abattoir, the five maids piling dripping chunks of carcasses into borrows, and closes with a more human slaughterhouse as Orestes raises his bloody hands to heaven. Conducting his first Strauss opera, Claudio Abbado wrings a harrowing performance from the peerless Vienna Philharmonic Orchestra. The music is infused with an eeriness and neurosis that heightens the emotions on stage. In the title role, Eva Marton gives an uninhibited and exultant performance, matched by that of Brigitte Fassbaender as her mother, Klytemnestra, murderer and widow of Agamemnon. Bejewelled from head to foot and consumed by the flames of guilt-ridden insanity, Fassbaender sings as if truly possessed. The more lyrical role of Chrysothemis is sung by Cheryl Studer, with a ragged and single-minded Orestes played by Franz Grundheber.
