Martha Mödl was a German soprano, and later a mezzo-soprano. She specialized in large dramatic roles such as Isolde, Brünnhilde, and particularly Kundry, and is considered, along with Astrid Varnay and Birgit Nilsson, one of the three major postwar Wagner sopranos. She was among the preeminent Wagner sopranos—and most compelling singing actresses—of the twentieth century. She was celebrated for her highly individualized interpretations, exceptional acting ability, intense stage presence, and "rich, sexy voice." Her career peaked in the early and mid-1950s, which included her Brünnhilde in Wilhelm Furtwängler's famous 1954 studio recording of Die Walküre and his 1953 live recording of Der Ring des Nibelungen, along with the title role from Fidelio with the same conductor also in 1953, and Isolde in Herbert von Karajan's 1952 Tristan und Isolde, live from Bayreuth. There have been fully ten recordings of her Kundry released commercially, most associated with the Bayreuth Festival, all from 1949 to 1959.
