Prometheus Quartet
Formed in the fall of 2023 at The Juilliard School, the Prometheus Quartet is a New York City-based string quartet inspired by the myth of Prometheus, striving to bring the gift of music to others. Just as Prometheus stole fire from the gods to gift to humanity, we aim to bring meaningful forms of connection to our audiences through performances of the beloved string quartet canon and undiscovered gems.
The quartet's current iteration formed after discovering an immediate bond while working on Korngold’s Piano Quintet in E Major in the 2024 Juilliard ChamberFest. Since then, the quartet coached intensively with Merry Peckham and was a Gluck Fellowship ensemble for the 2024-2025 school year. While at Juilliard, the quartet was coached by legendary cellist and chamber musician Joel Krosnick, Joseph Lin, Natasha Brofsky, and Catherine Cho. The quartet is currently the Graduate String Quartet in Residence at the University of Delaware where they are mentored by the Calidore String Quartet.
Additionally, the quartet has coached with members of Quatuor Ébène, the Alban Berg Quartet, the Jerusalem Quartet, Marc Danel, Timothy Eddy, André Roy, and appeared in masterclasses at the Chamber Music Society of Lincoln Center.
Festival appearances include being named the inaugural Emerging Artist String Quartet of Music Academy of the West in Santa Barbara, California, where they studied under the Takács Quartet, an educational residency at the Chamber Music Society of Fort Worth, the Schiermonnikoog Festival in the Netherlands, and the McGill International String Quartet Academy. Furthermore, the quartet were recently invited to compete in the 2025 Schoenfeld International String Competition and also took part in the Fischoff Competition.
Dedicated to innovation in the concert scene, the quartet also recently performed in “The Mad King,” a collaboration between Carnegie Hall and Juilliard’s “New Series” curated by music division dean David Ludwig. For this program, the quartet performed Schoenberg's Ode to Napoleon Buonaparte, Op. 41, in a multimedia setting alongside guest pianist Baron Fenwick and actress Ana Karneža. The quartet has also worked closely with Juilliard Arnhold Creative Associate, flutist Claire Chase, as part of her project Density 2036. Rated as one of New York Classical Review Critic’s Choice 2024-25 performances, the quartet premiered a new version of Terry Riley’s “Holy Liftoff” for string quartet, flute and electronic tape for Juilliard’s Fall Festival.
Upcoming concerts include performances at the Music Academy of the West’s Mariposa Series, Chesapeake Music, the University of Delaware, and in Chamber Music Society of Lincoln Center’s Inside Chamber Music series with Bruce Adolphe.
The quartet members individually attained their Bachelors degrees from Mannes School of Music, the New England Conservatory, the Peabody Institute, and the Eastman School of Music before forming at Juilliard.
