After making her debut at the Bayreuth Festival as Elisabeth in "Tannhäuser" in 1961, she devoted herself principally to a concert career. However, for the next twenty years, she continued to make occasional appearances in one of her favourite operatic roles, Bizet's "Carmen". She was among the first Spanish-born operatic singers to record the complete opera, having done so in 1958 in a recording conducted by Sir Thomas Beecham, using the recitatives added by Ernest Guiraud after Bizet's death. Though Carmen lay comfortably in her range, she nevertheless also sang major soprano roles, the best known of which were Donna Anna, Manon, Nedda, Desdemona, Cio-Cio-San, Mimi, Violetta and Mélisande.
