She appeared at the Metropolitan Opera in New York City from 1903 until 1914, specializing in Wagnerian roles. By that time she was singing as a dramatic soprano. Fremstad appeared before the public 351 times as a member of the Met's stellar roster, most frequently as Venus in "Tannhäuser", Kundry in "Parsifal", Sieglinde, Isolde and Elsa in "Lohengrin". American audiences never warmed much to her interpretation of the title role in Bizet's "Carmen", but she had sung the role opposite Enrico Caruso in San Francisco the night before the city was wrecked by the 1906 San Francisco earthquake and ensuing fire. (She and Caruso escaped the disaster unharmed.)
