In 1991, Yuji Takahashi and Mamoru Fujieda collaborated in staging a sound installation at the Sezon Museum of Art in Tokyo, making extensive use of the new artistic possibilities provided by the advent of personal computers. In this installation, a culmination of their investigations into the aesthetic use of new technology, these two renowned leaders of Japanese experimental music used sensors and transducers on objects and in the space itself, via MIDI conversion, to trigger pianos, synthesizers and samplers. The four pieces here were recorded for a cassette-only release timed to coincide with the exhibition. This release continues the EM Records investigation of the “cyber-occult” movement in early-90s Japan, in which the new personal digital technologies allowed access to previously hidden worlds, opening new realms for exploration. In the words of Takahashi, quoted from the original leaflet for the “Ikebukuro Cyber Café” event: “In the flickering time of everyday life, the translucent coordinate axes of the dark cyber space appear and disappear like a shimmering shimmer.” This hints at the quirky yet evanescent beauty of a very intriguing historical document which also happens to sound great. It is available on CD and DL with Japanese and English notes written by Koji Kawasaki, a leading researcher of Japanese electronic music.
