Marginal Consort has its origins in the East Bionic Symphonia — an ensemble formed at the radical Biggako School of Aesthetics under the tutelage of Kosugi Takehisa in the 1960s. Now a quartet of Kazuo Imai, Masami Tada, Kei Shii and Tomonao Koshikawa, Marginal Consort has historically played just one concert each year.
