We’re thrilled to welcome Opus13 as our new Quartet in Residence.

Thanks to our continuing partnership with Wigmore Hall, every three years we bring a world-class string quartet to Leeds for nine exciting performances.

Whether you’re a long-time chamber music lover or discovering it for the first time, this is the perfect opportunity to experience the next generation of outstanding performers.

First Prize winners at both the Wigmore Hall String Quartet Competition and the Bordeaux International String Quartet Competition in spring 2025, Opus13 is rapidly building a reputation on the international chamber music scene. Named after Felix Mendelssohn’s youthful and passionate A Minor Quartet, Op 13 – the first piece the ensemble ever played together – the quartet was formed in Oslo in 2014. Now based in both Oslo and Stockholm, Opus13 comprises Norwegian violinists Sonoko Miriam Welde and Edvard Erdal, plus violist Albin Uusijärvi and cellist Daniel Thorell, both from Sweden.

In addition to performing standard string quartet repertoire by composers such as Wolfgang Amadeus Mozart, Bela Bartók, and Franz Schubert, Opus13 is a passionate ambassador of Nordic classical and contemporary music, frequently performing works by Edvard Grieg, Wilhelm Stenhammar, Andrea Tarrodi, Britta Byström, and Sebastian Fagerlund.
