[Orb] orbert demo

Since the release in 1994 i've been a huge ...and i mean a huge FFWD fan. I bought the album in '94..its still my favorite ambient album ever. Now i found out there was a demo called orbert...i just found it on soulseek and downloaded it. Its also an amazing piece of music. The file that i have is a flac. file..51 min... Is this the whole demo or just a part of it? I hope someone can tell me more about it en when it was released..or made..
