Dutton made her European opera debut at Barcelona’s Gran Teatre Del Liceu and was reengaged by the theater for 10 seasons. She has sung several seasons at London’s English National Opera, most recently appearing as Kundry in Parsifal. That appearance marked the start of her career as a Wagnerian soprano, and she has since sung many of the major Wagnerian roles in the United States, Germany, and Hong Kong.

In the United States, she has sung Jordan Baker in John Harbison’s The Great Gatsby and Stephano in Roméo et Juliette, as well as numerous other roles for the Metropolitan Opera. In addition to her appearances in major U.S. opera houses, she has sung with more than 25 U.S. regional opera houses, in more than 30 different major roles.

Dutton’s orchestral work highlights include appearances with the New York Philharmonic, BBC Scottish Symphony, RTE National Symphony (Ireland), Prague Radio Symphony, Seattle Symphony, Houston Symphony, Indianapolis Symphony, and the Korean Broadcast Symphony at the United Nations General Assembly. She has recorded under the Chandos and Albany Records labels.

She has been awarded prizes in many competitions, including Placido Domingo’s Operalia. She earned her Bachelor of Music and Master of Music degrees from Indiana University, where she studied with famed Wagnerian Margaret Harshaw. Dutton earned an Artist Diploma from Yale University.

Of his recent portrayal of Prince Gremin in Eugene Onegin, Opera News applauded his ability “to create in his single aria and scene an impressive dignity.
