Following the widely acclaimed 3LP collection, Electronic Music from the Seventies and Eighties, Unseen Worlds has compiled a second, 2LP collection of favorite and unreleased Carl Stone works. Electronic Music from the Eighties and Nineties presents the soothing, hallucinatory side of Stone's slow-evolving, time-bending composition. While we can't always identify the source, we can hear that his sounds come from somewhere, and that there is a "correct" or "complete" version of them in theory; and so we can hear when they are being changed. What drives Stone's music is the flow that he draws out of those differences: the way an Indonesian gamelan morphs into a chorus built from one female vocalist over the course of "Mae Yao"'s twenty-three minutes, the surprise emergence of a Mozart chorus out of the synths and skip-glitches of "Sonali," or the slow, ambient evolution of "Banteay Srey". "Woo Lae Oak," issued in a single side edit for the first time, is an exception. Its samples - a tremolo string and a bottle being blown across the top like a flute - are simple in the extreme. Yet the Stone locates the inherent emotional properties of the sounds and takes them into unexpected expressive territory.
