The annual Christmas concert series at Oslo Cathedral, 'Klinge skal et jubelkor', has long been a highlight of the pre-Christmas period in Norway's capital city. Once every year, all of the choirs associated with the cathedral come together to perform a programme of Christmas music, from the youngest fledglings in the boys' choir to the veteran choristers who have sung at the cathedral their whole lives. Together with brass, timpani, harp, and two organs, the choirs perform Christmas carols central to the traditions of the Church of Norway. This recording of Oslo Cathedral's Christmas programme demonstrates that the cathedral continues to thrum with it's rich musical tradition.
