[A long-lost environmental music and electronic music CD is complete] The ambient works of the maestro Toshiya Sukegawa are unearthed. These are gems of music that filled office buildings and then vanished into the spaces of the city. *This release is sourced from about 50 master DATs (digital audio tapes) that were entrusted by Sukegawa, and, at the milestone of 11 years after Sukegawa's death, it brings together everything from full-fledged electronic music created at the NHK Electronic Music Studio to environmental music written to fill the spaces of corporate buildings. Most of the tracks are being released on CD for the first time, and previously unreleased recordings are also included. Comes with a commentary booklet (eight pages in all, in Japanese).
