This recording is the dark side of Bill Laswell at the peak of his art in 1995. He goes into a black trance. The piece is not from a collaboration, it was designed alone, in his studio in Brooklyn. Bass Terror Tetragrammaton is also to be linked to an alchemical process. Nocturnal Crawl is a totally hypnotic piece, the first that Nik Bullen designed outside of Napalm Death and Scorn. The two pieces answer each other strangely, like two sides of the same hidden anxiety.

The concept of this series was the confrontation of electric guitars as the tutelary instrument, but here and this time only, it came out of bassists confronting each other.
