At the Salzburg Festival, she appeared in 1969 as Marianne Leitmetzerin in Der Rosenkavalier by Richard Strauss,[1] and in 1970 as Barbarina in Mozart's The Marriage of Figaro in a production by Günther Rennert, conducted by Karl Böhm.
[5] On 20 August 1973, she was one of the sybils in the premiere of Carl Orff's De temporum fine comoedia at the Salzburg Festival, conducted by Herbert von Karajan, which was recorded.
[6] She sang the same year the soprano solo in Rossini's Petite messe solennelle at the Münchner Festwochen,[1] and the Lucerne Festival, with Wolfgang Sawallisch as the pianist and conductor, alongside Brigitte Fassbaender, Peter Schreier and Dietrich Fischer-Dieskau.
She sang regularly as a soloist in concerts with the Wiener Singverein, conducted by Walter Hornsteiner, such as Bach's Mass in B minor at the Stiftskirche Reichersberg, Franz Schmidt's The Book with Seven Seals at the Niederaltaich Abbey, and Bruckner's Te Deum in Passau Cathedral.
A reviewer noted of her performance of a dramatic aria in the latter work that "she shows her excellent range and instinct for theatrical combustibility".
She has also recorded Alban Berg's "Sieben frühe Lieder" in the orchestral version with the NDR orchestra conducted by Herbert Blomstedt available on DG.
