Opera Canada said of her performance in Il Trovatore: '"outstanding...mezzo-soprano Anne Ogan Larson, who teaches on the host college's faculty, but who could handsomely project Azucena's every note in a giant sized house as well."  Mrs. Larson has sung with the Des Moines Symphony, the Cedar Rapids Symphony, the Madison, Wisconsin and Tri-Cities Symphonies. She appeared as a riotous Thisbe in La Cenerentola, as the droll Martha in Faust, as Juno, Queen of the Gods, in the world premier of The Tempest, Marcellina in The Marriage of Figaro, Mama McCourt in The Ballad of Baby Doe, and most recently in the 25 th anniversary season of Des Moines Metro Opera as Mrs. Herring in Albert Herring.  Mrs. Larson performs often on campus and throughout the area in recital, oratorio, and opera.
