Unidentified Song

[Plazmater]

Sorry to ask another dumb question, but does anybody know anything about that song that plays while you are in the piggeh cell block? I have the MFP soundtrack, but it doesn't seem to be on there. You can also hear the sound when you're in the room with the iron butler (churning out dismembered torsos). You can hear a snippit of the song in this vid:
