heres a nice example of japanese minimal improv before its philosophical and process orientations forced a reductive tabularasa.
this is an organic soundmass comprised of tiny gestures held together by long silences and only dimmly perceptible washes that could almost be ambient noise from outside the musical environment.
this cd is out of print,im not even sure the slub lable still exists.
heres some info taken from the japanese improvised music pages.
Improvised Music from Japan / Mongoose
Mongoose was formed by Tetuzi Akiyama (guitar, electronics), Utah Kawasaki (analog synthesizer) and Taku Sugimoto (guitar) in 1998. Their music is "minimal noise music": free improvisation constructed from extremely quiet sound fragments generated by the three members. Thus, at the small venues where they usually have gigs, it often seems as if other sound elements--a telephone ringing, a door slamming, a chair squeaking, etc.--are part of their music (whether or not this is their intention).
Mongoose's first CD, At Penguin House, recorded live in February 1999, was released in September of that year. In October 2000, the group toured France and Belgium. This was the first time they played outside Japan.
