Archon Satani was a ritual ambient project from Sweden, formed in 1990, playing eerie and haunting industrial ambient music with a post-apocalyptic and sometimes bombastic feel. The original line-up consisted of Tomas Pettersson and Mikael Stravöstrand. They worked together from 1990 to 1993, then the former went on to form Ordo Equilibrio, while the latter continued under the name Archon Satani, as well as with his other project Inanna.
