Very interesting project - two Japanese noise masters (Aube/Nakajima and Monde Bruits/Iwasaki) are creating spacey/droney ambient which is quite moody and dark. Tracks are usually quite long and sounds are morphing into each other. On Sink/Assign CD, for example, what sounds like bell/wind chimes echoes are added to droning background which creates quite unusual effect. CD itself is similar to 108 by Aube, but its not as extreme.
Their complete discography include quite a lot of recordings, including "Atmos/Composure" LP for Korm Plastics and its quite hard to find most of them anywhere. However, for begginers, i would recommend "Sink/Assign" - especially if you're into drone-ambient or any form of experimental music.
