Violinist Nils Økland and keyboard musician Sigbjørn Apeland, musical partners for thirty years, have long been exploring the interfaces between traditional Norwegian music and improvisation. "Glimmer", an exceptionally beautiful album, takes the folk music of the western Norwegian region of Haugalandet as its starting point. Apeland's collection of pieces by local singers who have helped to keep the traditions alive forms the basis of the repertoire here, along with original compositions. The latter range from pieces written for a film about Lars Hertevig, the great Norwegian landscape painter of the 19th century, to music inspired by the modernist composer Fartein Valen. The combination of Økland's Hardanger fiddle and Apeland's harmonium is characterized by subtle timbres and a unique flow.
