Celebrating its 30th anniversary during the 2026–2027 season, Cuarteto Casals has established itself as one of the world’s leading string quartets and a defining presence in today’s international chamber music scene.

Founded in 1997 at Escuela Reina Sofía in Madrid, the ensemble appears each season at many of the world’s most prestigious concert halls and festivals, including Carnegie Hall in New York, the Philharmonie and Boulez Saal in Berlin, the Konzerthaus and Musikverein in Vienna, the Salzburg Festival, Wigmore Hall in London, the Concertgebouw in Amsterdam, the Philharmonie de Paris and Suntory Hall in Tokyo.

Its commitment to uncovering the essence of every score is reflected in more than twenty recordings for harmonia mundi, featuring works by Bach, Haydn, Mozart, Schubert and Brahms, as well as the complete string quartets of Beethoven and Shostakovich. This artistic approach also extends to historically informed performances using Baroque and Classical bows from the London-based Borletti Buitoni Trust. Alongside this, the quartet maintains a strong commitment to contemporary music through the premiere of new works and long-standing collaborations with today’s composers.

In its anniversary season, Cuarteto Casals once again serves as Artistic Director of the Barcelona String Quartet Biennial, presented by L’Auditori. The ensemble also gives the premiere of a new string quartet by Raquel García-Tomás, jointly commissioned by Centro Nacional de Difusión Musical (CNDM), the Kölner Philharmonie and the Musikverein Wien.

Highlights of the 26-27 season features tours across Asia and North America as well as extensive performances across Europe, with concerts at renowned venues such as a tribute concert for the 150th annivesary of Pau Casals’ birth at Palau de la Música in Barcelona, Bozar, Het Muziekgebouw in Amsterdam, Pierre Boulez Saal in Berlin, Auditorio Nacional de Madrid, Kölner Philharmonie, and Amici della Musica di Firenze.

Alongside its performing career, Cuarteto Casals is deeply committed to teaching and holds residencies at the Scuola di Musica di Fiesole, the Escola Superior de Música de Catalunya and the Royal Conservatoire The Hague. The ensemble has received Spain’s National Music Prize, the Medal of Honour of the Escuela Reina Sofía, Catalonia’s National Culture Prize and the Barcelona City Prize.
