American mezzo-soprano Rebecca Ringle Kamarei, known for her “outstanding” (The Washington Post) voice of "otherworldly luminousness" (The New York Times) has earned acclaim for international opera and concert performances. Engagements for 2022-2023 included returns to the Metropolitan Opera for productions of La Traviata and The Hours, and to Bard Music Festival for their retrospective on Rachmaninoff. During the 2021-2022 season, she returned to the Metropolitan Opera for productions of Elektra, Hamlet, Rigoletto, and Akhnaten, performed at Bard Music Festival’s celebration of composer Nadia Boulanger, and appeared in recital with pianist Bryan Wagorn at the renowned Aspect Chamber Music Series in works by Gustav and Alma Mahler. On the concert stage, she performed four programs celebrating Erich Korngold with Bard Music Festival and Orchestra NOW, and Ravel's 3 poèmes de Stéphane Mallarmé with the Norwalk Symphony. Outside of the classical music world, Ringle Kamarei curated repertoire and sang in works by artist Tara Subkoff as part of the Art Basel and PERFORMA art festivals in Miami and New York.

During this period, Ringle Kamarei spoke virtually with singers from her alma mater, Yale School of Music, and with students of the acclaimed Brooklyn Youth Chorus, also performing virtually on that ensemble’s year end gala. Performances in the 2023-2024 season include Bach cantatas with the Philadelphia Chamber Music Artists’ renowned Gamut Bach Ensemble, Mahler’s Resurrection Symphony with the New Mexico Philharmonic, and Beethoven’s 9th Symphony and arias and ensembles from grand opera with South Florida Symphony.
