In 1969, she gave up her repertoire of heavy dramatic soprano roles and began a new career singing mezzo roles. After being the world's leading Elektra for over twenty years, she now established herself as a great interpreter of Klytemnestra. The role of Herodias in "Salome" became her most often-performed role: 236 performances. She returned to the Metropolitan in 1974 and last appeared there in Weill's "Rise and Fall of the City of Mahagonny" in 1979. In 1975 she appeared as Herodias in the production of Salome with Teresa Stratas which was filmed with the Vienna Philharmonic and directed by Gotz Friedrich.
