At the Metropolitan Opera New York she made her debut in 1976 singing Eva in Die Meistersinger von Nürnberg.

Ms. Marton has become one of the leading interpreters of Brünnhilde in Wagner's Ring,  however Brünnhilde is just another heroine in the extensive gallery of her definitive interpretations that also include the title roles of Salome, La Gioconda, Leonora in La Forza del Destino and, most of all, the title role of Puccinis last opera Turandot which she first sang at the Vienna State Opera in 1983. Since then she has been hailed simply as "the Turandot of today", and has sung this role nearly 200 times and with every major opera company including the Metropolitan Opera, La Scala, Arena di Verona, San Francisco, Chicago, Barcelona, Houston, Washington, in six different TV and video productions, including one from the Vienna State Opera directed by Harold Prince, one from the Metropolitan Opera in a spectacular Franco Zeffirelli production and in a production designed by David Hockney and filmed at the San Francisco Opera.
