4℃（2004〜2006）
A project which was begun in 2004 by showing noise improvisation with roaring sound in a concert hall where the space was completely dark (New York P.S.1 contemporary art center web radio sponsored by WPS1). When the music has completely saturated the space, it transforms the space itself, just like 4 degree Celsius water (which has the characteristic that mass per 1cc becomes the greatest (1g) for every temperature). By the year of 2006, visuals and a contemporary dance were added to it, performed as a complete edition, and proposed the saturation of space with even more information in it.
Graduation work at Tokyo University of the Arts.
