This special edition is added a CDR Music for Exhibition Space No.1 composed by Kuniharu Akiyama. Two descriptions High and Chic Fair and Oct. 26, 1963 were on envelope of original tape. But detail of the event is unknown.

Several tapes that were discovered at Aki Takahashi's house and audio sources that have been put on hold until now are being released collectively. The time periods and contents of the sounds vary, and most of the detailed data are not known. Nevertheless, the contents are all very intriguing, including live recordings by Hiroyoshi Suzuki from the days of "Jikken Kobo" (Experimental Workshop), never-before-heard works by Toru Takemitsu, and the strange electronic music of Joji Yuasa. We decided to leave the analysis to the researchers and introduce these sounds to shed light on them.
