Nao Nishihara challenges the ears, exploring relation and disrelation between sound and human being. Performance group Tsumugine, founded by Yasuno Miyauchi, combines the audience, space and its acoustic, as becoming a background scenery themselves. Both of them use sound as their medium, sharing the keywords such as human, sound, music, communication and body. While Nishihara deconstructs music relying on ears, Tsumugine attempts to pick up each sound around the world to start constructing something new. Presenting their performances in parallel, audience will witness those kinds of performance/music that are most needed in today.
