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 the breadth of Yoshimatsu’s work - solo, ensemble, and in composition for labelmates - we see a remarkable generosity of musical talent. Some records (such as those produced for Fumie Yasamura, represented here in “Violet” and “Escape”) are formed of hazy, gliding 4-track pop songs coursing with hallucinogenic electricity. Others, such as 1982’s Poplar (and its namesake track on this collection), combine bucolic nylon-string guitar rambles, vibrantly coloured with sequenced MIDI arpeggiation and the dulcet bloops of early computer programming. Deeper still, “Pastel Nostalgia”, from the 1983 album of the same name, marries childlike piano with a wailing siren tone and dripping tap percussion. It is significantly creepier, more acerbic and disembodying than the ambient or New Age music of the era, despite a similarity in raw materials.

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.
