From around 1998 Yamazaki Maso started to incorporate trippy, spacey electronic elements into Masonna performances. In order to better pursue these elements alone, in 2000 he started Space Machine, his self-labeled "analog electronic cosmic sound project". For as long as he had been performing under the Masonna moniker, Yamazaki had been ardent fan of early electronic music from the 50s and 60s, and in order to research the impact that electronic sounds had upon the spiritual lineage audible in sixties US and British psychedelic music and seventies krautrock, Yamazaki began collecting analog synthesizers and vintage electronic equipment. He continuously experimented with these instruments in his home studio, and while groping towards an understanding he discovered a new direction for his own music, a direction different from his work as Masonna. In 2000 Yamazaki was forced to temporarily cease Masonna activities due to ill health, and this allowed him to concentrate more fully on Space Machine.
