I think this one below may be 1998 (or even earlier). The vocalist sounds like Jan Johnston but it's definitely not her as I checked. She says "reality of dreams" and found a track on Discogs called Waveform - Reality of Dreams. Unfortunately the one rip that I managed to obtain doesn't sound like it.
