Ecor Quartet
The Ecor Quartet brings together four dynamic musicians—Sahada Buckley (violin), Trace Johnson (cello), Yujin Lee (piano), and Chadwick Thomas (clarinet)—to create vibrant and expressive chamber music. Individually, each player is an active performer thriving as a chamber musician, orchestral player, recitalist, and educator.
With members based in Madison, Wisconsin and Hartford, Connecticut, the quartet’s journey began in Maine at Atlantic Music Festival in 2022, where the members first performed together as AMF fellows and members of the AMF Contemporary Ensemble. Their collaborative chemistry was immediately evident, which led to plans for future collaboration. In 2023, Sahada and Trace founded the Eastern Shore Chamber Music Festival, where the quartet continues to perform each summer.
With its distinctive instrumentation—clarinet, violin, cello, and piano—the Ecor Quartet explores a wide array of repertoire, from lesser-known gems of the twentieth century to cutting-edge contemporary works. Their performances are rooted in a shared passion for chamber music and an unwavering commitment to creating connection through music.
