Otakar Olšaník / Jan Martiš

Heads have been after Otakar Olšaník and Jan Martiš's Advanced Process for a long time. That's because "coincidentally-cosmic disco" packed with spaced-out, smacky-synth dynamite tends to become sought-after. Originally slipping out on the mighty Coloursound in 1986, the label described the sound as "contemporary synthesizer underscores played by computers; depicting future technologies in today's process." If they'd just added "acid-drenched", they'd have been closer to nailing it.
