Dumb Type

Since the founding of DUMB TYPE, Yamanaka has primarily been responsible for music production, while the late Furuhashi played a crucial role in translating Yamanaka’s compositions into stage direction. Their collaboration began with previous groups ORG and R-STILL, and was influenced by the NEW WAVE and progressive rock trends they were pursuing at the time, as well as by artists like Laurie Anderson, Meredith Monk, and Robert Wilson, who fused minimal music and avant-garde performance. Moreover, their bold incorporation of cutting-edge sampling and house music during that era laid the foundation for DUMB TYPE's sound, marking an important intersection in the history of minimalism, ambient music and performance art in Japan.

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.
