This sparkling collection of folk dances from Norway and Sweden, offset by two Estonian chorales and three improvisations, comes from two of the finest practitioners of this kind of material: Gunnar Idenstam, playing on the new Klais organ of Kristiansand Cathedral in southern Norway, and Erik Rydvall, on the nyckelharpa, the keyed folk fiddle of Sweden. The combination of rhythmic vigour, the harmonic ambiguity of Scandinavian folk music and the huge range of instrumental colour gives these tunes – all in spontaneous, semi-improvised performances – an irresistible and immediate appeal.
