Opus13 Joins Kirshbaum Associates for North American Representation

“This was a performance of a profundity and kaleidoscopic colour that would have been astounding from any ensemble, let alone a young one still making itself known.”
– Gramophone

First Prize winners at the 2025 Wigmore Hall International String Quartet Competition and the Bordeaux International String Quartet Competition, Opus13 are rapidly building a reputation on the international chamber music scene. In 2026 they were named recipients of the prestigious Borletti-Buitoni Trust Award and are BBC New Generation Artists for 2026-2028.

Named after Mendelssohn’s A Minor Quartet, Op. 13 — the first piece they ever played together — the quartet was formed in Oslo in 2014 by Norwegian violinists Sonoko Miriam Welde and Edvard Erdal, and violist Albin Uusijärvi and cellist Daniel Thorell, both from Sweden.

In addition to performing core string quartet repertoire, Opus13 are passionate ambassadors of Nordic classical and contemporary music, frequently programming works by Grieg, Stenhammar, Tarrodi, Byström, and Fagerlund. They also enjoy genre-crossing collaborations, having performed with Norwegian folk and popular music artists including Gjermund Larsen Trio, Sissel Kyrkjebø, and Sver.

Opus13 are the founders and artistic directors of Vinterspill på Lillehammer, an annual chamber music festival in Lillehammer, Norway.
