First of all a big big shout out to Edition Omega Point : An outstanding store located , well unfortunately I can not read Japanese , but somewhere in Japan , they also do mail order http://homepage2.nifty.com/paganmusik/omega/top.html , top store !!!!!Brilliant to finally make these remarkable recordings available for the public (Limited to 500 copies worldwide) .
Aoi no ue was composed 1961 for voice and tape and based on The tales of Genji written by Murasaki Shikibu in 11th century. My blue sky (No.1) composed 1975 for tape. Highest recommendations !!!!!
