新日本フィルハーモニー交響楽団
After her one-year reign, Powell embarked on a singing career, debuting with Seattle Opera in the role of Adele in Die Fledermaus. Calling her performance the "major surprise of the evening," a reviewer from Opera Canada praised "her sparkling stage personality" and pronounced her technique as "fully up to Adele's coloratura requirements." Powell's opera career took her to the New York City Opera to the New Japan Philharmonic. She has sung as a soloist for John Williams and the Boston Pops.
