Harthouse and Eye Q - giants of trance. Most of their decent releases have found their way on to various compilations and re-releases over the years, but as far as I can tell, these two tracks have only ever appeared on vinyl as b-sides.
The a-side is a bit cheesy, with some girl whispering something about feeling her desire - not my cup of tea. The Tronic mix is proper trance; killer bassline, some nice pads and a main melody that's not too dissimilar to Sourmash's "Pilgrimage To Paradise" (released the year before). But unlike Sourmash (which was veering towards the hard house side of trance), the melody on this mix of "Desire" sounds like it was written by aliens to fuck with your acid dazzled mind.
