Gish soundtrack?

Is there anywhere I can find out who made the Gish soundtrack, and if they have a CD? I wrote to GameAudioMagic.com but they never wrote me back. I'm also wondering if there's any chance they're the same people who worked on Hiroyuki Nanba's Genso Suikoden Ongakushu album...

Thanks!

All the music for Gish was created by Estradasphere or some of it's members .  Most of the songs were changed a bit for Gish.
