The Oslo String Quartet (OSQ) was founded in 1991 and is one of Scandinavia’s most acclaimed and sought after chamber ensembles. In 1994 they made their international mark after making the finals of London International String Competition, and by 1999 their complete recordings of string quartets by Grieg and Carl Nielsen attracted attention, the latter being selected as Editor’s Choice in the prestigious Gramophone magazine. As well as being regular guests at all the major chamber music festivals and series in Norway and Scandinavia, OSQ tours Europe and America. 30 years of artistic work is shown in the discography of OSQ which contains both classic and modern masterpieces. OSQ regularly collaborates with composers, which has resulted in several awards. Music from many different genres exquisitely arranged for string quartet by their own cellist Øystein Sonstad is an important part of their artistic scope. Connecting with a broad audience has always been important for the Oslo String Quartet. School concerts, mini-festivals and video productions with specially adapted programs and themes have been a vital part of their activity for three decades. Some productions include: Beethoven show for children, the festivals «The Beethoven Code», “G-force” and “Schubert Mysteries”. Lately the video series «The Corona Mystery», presenting a humorous glance at our pandemic situation. OSQ plays on instruments generously on loan with by Dextra Musica Foundation.
