Sounds like those Richard Strauss unleashed in Elektra with a gigantic orchestra were unprecedented until the opera’s premiere in 1909. And the radicalism and expressive ferocity of Elektra have lost none of their power to this day. The archaic subject matter both terrifies and fascinates: Elektra, an infinitely lonely young woman, is kept alive solely by the thought of avenging her mother’s murder of her father, Agamemnon. When her father is avenged and her brother Orestes has killed their mother and her lover, Elektra dances an ecstatic dance, at the climax of which she collapses dead. This is a roller coaster of an opera. Ricarda Merbeth, one of the most important Wagner and Strauss interpreters of our time, takes on the title role, while the charismatic Okka von der Damerau makes her debut as Clytemnestra. The Slovak conductor Juraj Valčuha, for years one of the most influential guest conductors at Deutsche Oper Berlin, conducts the monumental work.
