Myself, and others, have been trying to ID this fascinating tune for years - I've only ever heard it played once, by DJ SY, in this mix (DJ SY, Fibre Optic, Flying High, 1994) - DJ SY himself has been asked apparently, and even he couldn't ID it, so the hope of ever finding out is fading! But hopefully someone on here can save the day...
(The tune really gets going at 1:18)
