The Marginal Consort is a Japanese experimental ensemble comprised of Kazuo Imai (今井和雄), Yasushi Ozawa (小沢靖), Tomonao Koshikawa (越川知尚), Kei Shii (椎啓), and Masami Tada (多田正美). The ensemble meets and performs once a year since 1997. They don't rehearse or talk in between these annual concerts. The members of Marginal Consort met in art school in 1970's Japan. They create elaborate instrumental systems from household items and hardware-store materials. {{youtube>v=1ACObnP0QGM}} ===NOTES=== in 2018 they gave a lecture at CalArts which I attended.
