The Calidore String Quartet has been praised by the New York Times for its “deep reserves of virtuosity and irrepressible dramatic instinct.” The Los Angeles Times described the quartet as “astonishing,” their playing “shockingly deep,” approaching “the kind of sublimity other quartets spend a lifetime searching” and praised its balance of “intellect and expression.” Recipient of a 2018 Avery Fisher Career Grant and a 2017 Lincoln Center Emerging Artist Award, the quartet first made international headlines as winner of the $100,000 Grand Prize of the 2016 M-Prize International Chamber Music Competition. The quartet was the first North American ensemble to win the Borletti-Buitoni Trust Fellowship, was a BBC Radio 3 New Generation Artist, and is currently a season artist at the Chamber Music Society of Lincoln Center.

In summer 2021, the Calidore made debuts at the Sarasota, La Jolla, and Saratoga Music Festivals as well as the Schubert Club of St. Paul, MN. Highlights of the 21-22 season include returns to Wigmore Hall, Alice Tully Hall, and the Philadelphia Chamber Music Society.

The ensemble will premiere a new work by composer Huw Watkins commissioned by Wigmore Hall and will collaborate with the Emerson Quartet and pianists Jeffrey Kahane, Henry Kramer, and Gabriela Fahnenstiel.

The Calidore String Quartet’s second album for Signum Records, entitled BABEL, was released in 2020 and features worksby Schumann, Shostakovich, and Caroline Shaw. The Strad selected the album as the “Editor’s Choice” and praised it as “breathtaking…a universally impressive disc.” The quartet’s other recording for Signum is 2018’s Resilience including quartets by Mendelssohn, Prokofiev, Janácek, and Golijov.

The Calidore has given world premieres of works by Caroline Shaw, Hannah Lash, and Mark-Anthony Turnage.

The Calidore String Quartet was founded at the Colburn School in Los Angeles in 2010. Within two years, the quartet won grand prizes in virtually all the major US chamber music competitions, including the Fischoff, Coleman, Chesapeake, and Yellow Springs competitions, and it captured top prizes at the 2012 ARD International Music Competition in Munich and the International Chamber Music Competition Hamburg. An amalgamation of “California” and “doré” (French for “golden”), the ensemble’s name represents its reverence for the diversity of culture and the strong support it received from its original home: Los Angeles, California, the “golden state.”
