“Eau” is the lovely new album from aus, the solo project of Tokyo-born composer and producer Yasuhiko Fukuzono, who has gained attention, in Japan and overseas, for his thoughtfully paced and sensitively skillful music as well as his intriguing sound design for exhibitions and experimental cinema. Having worked primarily with keyboards and electronic sound up to this point, “Eau” is a slight yet fascinating shift for aus; the album, while still primarily an electronic work, revolves around the sonic world of a stringed acoustic sound source, the koto, that most characteristically Japanese of musical instruments. The very accomplished Eden Okuno provides the delicate-yet-rich koto sounds on offer here; Fukuzono, in the liner notes, acknowledges the importance of Okuno’s artistry to the project.
The compositions on the album are designed to balance the sound of the koto, with its subtly variable attack and flickering resonance, with the timbre of other instruments. The delicate decay and metrical flexibility of the koto is enveloped by sustained synthesizer sounds and contrapuntally constructed piano melodies, creating a flowing ambience with absorbing undercurrents, a languid and liquid quality that reveals the suitability of the title.

Avid fans of contemporary Japanese music might hear the influence of pioneering works such as the the 1979 Hiroshi Yoshimura composition “Clouds for Alma”, realized by koto player Tadao Sawai, and the 1993 album “Koto Vortex I: Works by Hiroshi Yoshimura” which featured performances of Yoshimura’s works by the Japanese koto quartet Koto Vortex. These works attempted to remove the koto from its traditional context and place it within the context of ambient and techno. “Eau” is available on CD/LP/cassette/digital, with E/J liner notes by aus. “Eau” is the first collaborative release by EM Records and FLAU, the label run by Yasuhiko Fukuzono (aus).
