Toru Yamanaka, Teiji Furuhashi, Dumb Type

In the performance of this work, "Plan for Sleep" (1986), created simultaneously with “Every Dog Has His Day” (1985), Yamanaka took on the role of sound operation. The performance begins with a minimal piece where the tones of the electronic organ and striking phrases from the piano and saxophone race forward in syncopation. Following this, various sound fragments drift over a deafening industrial beat reminiscent of machine noises. There are also pieces that transform the typing sounds of a typewriter into rhythm, showcasing a range of experiments inspired by the then-novel sampling technology, beautifully intertwining with the physicality of the performance.

Additionally, influenced significantly by film music, Yamanaka incorporates a rich tapestry of colors through melancholic melodies that evoke various scenes, from secular jazz to other influences. This work constructs a uniquely original and sophisticated worldview that stands out even when surveying the canon of avant-garde performance art from around the globe in the postmodern era.
