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.

After aging the past 24 years, Nils Henrik Asheim’s work “Salmenes bok” (“The Book of Psalms”) has now been released. The hour-long work was written for the dedication of Oslo Cathedral’s new Ryde & Berg organ in 1998. It features both organs in the cathedral (with Kåre Nordstoga on the choir organ and Asheim playing the main organ) to create a surround sound around the choir singing 21 texts from the biblical Psalms in a rich tonal language equally rich in contrast. The result is a unique listening experience, a magical fusing of voices and organ.
