Two of Henning Christiansen’s tape works from the 1980’s, 'Peter der Große op. 174' (1986) and 'Gudbrandsdal op. 178' (1987), are now released for the first time by the Institute for Danish Sound Archaeology. Originally composed for different contexts – 'Peter der Große' as the score for a German radio feature and 'Gudbrandsdal' for a performance in collaboration with Joseph Beuys and later Bjørn Nørgaard – the two works stand out in Christansen’s extensive and many-faceted oeuvre by employing almost entirely electronic sounds.
