Mezzo-soprano Annie Rosen's performances have been acclaimed as “fearless,” “intensely present,” and “soul-crushingly vulnerable.” This season she debuts as the title role of The Maid of Orleans (Opera Company of Middlebury) and of L’enfant et les sortilèges (Florentine Opera), returns to the Metropolitan Opera as Ankhesenpaaten/Akhnaten and to the Lyric Opera of Chicago as Taller Sister/Proving Up, and covers Guinevere/Le roi Arthus at Bard Summerscape. Some of her pandemic projects included full-length films of Hansel and Gretel (Opera Ithaca) and Taking Up Serpents (Chicago Opera Theater), as well as live streaming recitals from balconies across Chicago.

An aficionado of new and experimental work, Rosen joined the Lyric Opera of Kansas City's Explorations series in 2019 to present a fully staged version of Sarah Kirkland Snider's one-woman song cycle Penelope. Other fringe work has included a collaboration with L.A.-based director Annie Saunders and the International Contemporary Ensemble to help create The Wreck, a site-specific devised opera based on the poetry of Anne Sexton and the compositions of Mariana Sadovska; a fully staged interpretation of Gyorgy Kurtag's Kafka Fragments for solo voice and solo violin in New York City, which OperaNews hailed as “a flat-out triumph for its two fearless performers"; and a collaboration with the Hong Kong Ballet in Kurt Weill's Die Sieben Todsünden.
