Cult Japanese outsider composer K. Yoshimatsu’s key 1980’s works are collected and reissued for the first time on new career retrospective Fossil Cocoon, binding ambient, abstract punk, music concréte and purist songwriting into a single unified artform.

Over a furiously prolific period from 1980 to 1985, K. [Koshiro] Yoshimatsu composed, recorded and released some forty albums in the span of a few years. These records primarily appeared under his own name, some required aliases, and others saw him compose, arrange, and produce for friends and peers in his creative circle. All of them, however, surfaced on Japan’s cult and inimitably fertile DD. Records, an astonishingly exhaustive catalogue once described as “the most amazing DIY effort ever undertaken to document an alternative music scene”. Led by close Yoshimatsu associate T. [Tadashi] Kamada, DD. Records released exactly 222 cassettes of brazenly, addictively weird Japanese outsider music over a period of five years, each with typewritten liner notes and enigmatically constructed Xerox artwork of found materials. The cassettes remain the stuff of collectors’ dreams, fetching astronomic prices on the rare occasions they surface in record stores or private sales. However, a keen archivist, Koshiro Yoshimatsu’s master recordings remained in his possession (a not unreasonable outcome given that his work was all self-recorded in his home) and meticulously filed, ready for rediscovery.

Yoshimatsu’s substantial catalogue now happily, newly sits in a neat collection as Fossil Cocoon, compressing his enormous abilities into single moments. Koshiro himself was an invaluable lighthouse throughout the curation process, a guide through the depths and annals of his recording career, now forty years hence, shining light onto forgotten music rescued from home-recorded tapes. The result may be an expressly varied album, but it is held magically together by Yoshimatsu’s profoundly singular creative alchemy.
