The members of the quartet are violinists Adrian Steele and Phoenix Avalon, violist Devin Moore, and cellist Joshua McClendon. The four began as an ensemble at the Juilliard School, and following a break during the global pandemic reconvened at the Kneisel Hall Chamber Music Festival in the summer of 2021 under the tutelage of Joel Krosnick.  In addition to Mr. Krosnick, the ISQ has coached with Joseph Lin, Astrid Schween, Laurie Smukler, Joseph Kalichstein, Roger Tapping, Misha Amory, Timothy Eddy, Donald Weilerstein, Atar Arad, Robert McDonald, Christoph Richter, Miriam Fried, and Paul Biss.

Winners of a 2023 Avery Fisher Career Grant, and the 14th Banff International String Quartet Competition in 2022, the New York City-based Isidore String Quartet was formed in 2019 with a vision to revisit, rediscover, and reinvigorate the repertory.  The quartet is heavily influenced by the Juilliard String Quartet and the idea of ‘approaching the established as if it were brand new, and the new as if it were firmly established.’

The Isidore Quartet has appeared on major series in Chicago, Pittsburgh, Seattle, Durham, Washington (JFK Center), San Antonio, Toronto, Montreal, and Ottawa, and has collaborated with a number of eminent performers including James Ehnes, Jeremy Denk, Shai Wosner, and Jon Nakamatsu.  Their 23/24 season will feature appearances in Berkeley (Cal Performances), Boston (Celebrity Series), Washington DC (Phillips Collection), New York (92nd St. Y), Chicago, Baltimore, Ann Arbor, Denver, Houston, Indianapolis, Tucson, Phoenix, Santa Fe, La Jolla, Aspen, Vancouver, Calgary, Edmonton, and at Dartmouth College, and Spivey Hall in Georgia, among many others.  European highlights include Edinburgh, Lucerne, Brussels, Amsterdam, Hanover, Frankfurt, and Hamburg’s ElbPhilharmonie.

Outside the concert hall the quartet has worked with PROJECT: MUSIC HEALS US providing encouragement, education, and healing to marginalized communities - including elderly, disabled, rehabilitating incarcerated and homeless populations - who otherwise have limited access to high-quality live music performance.  They have also been the resident ensemble for the Contemporary Alexander School/Alexander Alliance International.  In conjunction with those well-versed in the world of Alexander Technique, as well as other performers, the ISQ explores the vast landscape of body awareness, mental preparation, and performance practice.

The name Isidore recognizes the ensemble’s musical connection to the Juilliard Quartet:  one of that group’s early members was legendary violinist Isidore Cohen.  Additionally, it acknowledges a shared affection for a certain libation - legend has it a Greek monk named Isidore concocted the first genuine vodka recipe for the Grand Duchy of Moscow!
