I'm looking for the track 'Circulus Vitiosus' by Psilocybin.

The last track played at a goa party in Belgium was so good some people asked the dj which one it was. The only info he gave was that it was called "Circulus Vitiosus". The only link between that name and trance is one towards these forums, where a member (Snooper) mentioned the track 'Psilocybin - Circulus Vitiosus' as one of Oliver Lieb's best tracks. Does anyone know where I can hear this peace of music again? I would like to buy it, but I don't think it's released.

Thanks in advance!
I will post here more often...
