Above all in Italy and in Berlin, she gained a great reputation "because of her rich, expressive and seemingly never-ending alto voice".
After the Second World War she gave guest performances at the Teatro la Scala, in Rome and Vienna.
During guest performances in the great music centres of the world (Vienna, Munich, Berlin, Paris, London, Buenos Aires, Moscow) she was celebrated as an esteemed alto.
She participated in recordings of Verdi's Requiem, Beethoven's Missa solemnis and Rossini's Stabat mater for the Deutsche Grammophon label.
"Her repertoire was wide and eclectic, and especially her song recordings show the emotional and interpretative maturity of the artist".
