In 1989, Snorre Westvold Ruch (born January 21, 1972), also known under the stage name Blackthorn, and Marius Vold formed the band Stigma Diabolicum and recorded one demo.
In October 2007, Greek label Kyrck Productions released the Stigma Diabolicum compilation, which featured both the Grymyrk and Trøndertun demos, as well as material from the Stigma Diabolicum demos Lacus de Luna and Luna de Nocturnus and two tracks ("Thule" and "Fall") from a 1991 Thorns rehearsal.
The project was started in 2003 by Finn Olav Holthe (of The 3rd and the Mortal), Jon Wesseltoft and Snorre Ruch to explore the aesthetics of sound and its influence on the listener, using multichannel playback systems and various audio preparations.
The band first produced sound for Norwegian visual artist Bjarne Melgaard's works displayed at the Playlist exhibition at the Palais de Tokyo in Paris in 2004.
Ruch and Holthe had previously contributed sound to Melgaard's Interface to God exhibition at Kunsthalle zu Kiel in 2002.
