Oslo chamber orchestra was founded in 1957. The orchestra has since the beginning annually performed 4-8 concert programs ranging in style from early baroque to contemporay music. Several Norwegian composers have dedicated works to the orchestra, e.g. Antonio Bibalo, Tor Brevik, Tore Brunborg, Vagn Holmboe, Mikko Heinö, Sigurd Berge, Vigdis Johnsen and Rolf Inge Godøy.

For the last 10 years, Oslo chamber orchestra has dedicated many concerts to the rich growth of musical talent in Norway. Young conductors and/or soloists have been invited to rehearse and make concert presentations with the orchestra. Many musicians who now have leading positions in orchestras or as soloists remain friends with Oslo chamber orchestra. Among them are Øyvind Bjorå, Sigyn Fossnes, Aja Humm, Katharina Hager-Saltnes, Jørn Halbakken, Ketil Grøtting, Ragnhild Hemsing, Sigurd Imsen, Victoria Johnson, Øystein Jæger, Florian Kellerhals, Helge Kjekshus, Christian Kjos, Bård Monsen, Hans Petter Mæhle, Anders Kjellberg Nilsson, Per Kristian Skalstad, Peter S. Szilvay, Gustavo Tavares and Cathrine Winnes Trevino.

Many of the members of Oslo chamber orchestra are working with music in one form or the other; teaching violin or cello, composing, working with musical therapy and as a concert organizer. Others are working in very different parts of the Norwegian society: professor, poet, environmental expert, health experts, civil engineer, librarian... altogether this variety of background united in the love for music creates a lot of energy and vitality to the music as well as to the audience.
