Now in his 70s, the uncompromising Arne Nordheim may be Norway’s closest equivalent to Stockhausen. The 12 pieces collected in this beautifully packaged CD-standing out even among Kim Hiorthoy’s typically beautiful design work-offer spacious musique concrete miniatures from the late ’60s/early ’70s. Defying the Norwegian trend of the time towards neo-folk classicism, Dodeka is strung through with an ambient spirit of hovering tintinabulation. In this, it comes closest to approximating a music box concerto of fluttering analog seagulls. Rarefied and beguiling.
