n Christian symbolism, the rose is closely associated with the Mystery of the Nativity, and therefore with both Jesus Christ and Mary. The idea of the perfect flower, springing forth from a thorny stem, has - like the Nativity itself - captured the imagination of poets and musicians throughout the ages and from all stations of life. With this original and wide-ranging Christmas collection, Grete Pedersen - the artistic director of the Norwegian Soloists' Choir - has created what might be compared to a rosary, combining 12th-century hymns by Hildegard of Bingen with a carol by the Danish 20th-century composer Per Nørgård, as well as traditional Christmas psalms, in many cases sung to Norwegian folk tunes following age-old usages. Grete Pedersen and the choir have reached a wide international audience through four previous discs on BIS, ranging from collections of Grieg, or of Brahms and Schubert, to the folk-inspired White Night and, most recently, Refractions: the unexpected combination of three 20th-century giants - Berg, Webern and Messiaen - with their Norwegian contemporary Fartein Valen. On the present disc, the team is once again joined by the singer Berit Opheim and the violinist Gjermund Larsen - both with a background in folk music - as well as by Rolf Lislevand, internationally acclaimed lutenist, and the highly respected jazz bassist Bjørn Kjellemyr.
