Karl Böhm
Several of her most notable recorded roles in Mozartian opera include Susanna in "Le nozze di Figaro" for the Deutsche Oper Berlin with Karl Böhm conducting, as well as Ilia in "Idomeneo" with the Staatskapelle Dresden. A re-released recording of "Don Giovanni" with the Vienna Philharmonic and Karl Böhm from the 1977 Salzburg Festival features her in one of her best-known roles, Zerlina. A performance by Mathis as Cherubino is available on a DVD from the Salzburg Festival of 1966, with the Vienna Philharmonic under Böhm, where she sings alongside Ingvar Wixell, Claire Watson, Reri Grist, and Walter Berry.
