Opus13, an acclaimed string quartet formed in Oslo in 2014, comprises Norwegian violinists Sonoko Miriam Welde and Edvard Erdal, along with Swedish violist Albin Uusijärvi and cellist Daniel Thorell. Named after Mendelssohn’s passionate A Minor Quartet, Op. 13—the first piece they performed together—the ensemble has rapidly gained international recognition. In 2025, they secured First Prize at both the Wigmore Hall and Bordeaux International String Quartet Competitions. Opus13 masterfully interprets standard repertoire by composers like Mozart, Bartók, and Schubert, while also championing Nordic classical and contemporary works by Grieg, Stenhammar, Tarrodi, Byström, and Fagerlund.
