Hybrid released the limited edition double a side ‘Gravastar / Celebrity Science’ on 25th November 2002.

Dotmusic says:

"Essentially 'Gravastar' is a mid tempo, fat piece of chunky four four with a dark growling synth line. It begins minimally and starts a slow build into a funky but melodic progressive trance floor-filler, garnished with chirping percussive melodies and sweeping filters.

'Celebrity Science' is equally dance floor orientated but this time on a breaks tip, using abrasive sounds and highly polished effects over an epic, tempo increasing build.

As ever this is a heavily polished production."
