Etat Brut is a pioneer industrial/noise band from Brussels that operated from 1979 until 1983. The duo (Phillippe x and Philippe X, today academic scientists) released a dozen of cassettes, various flyers and xeroxed booklets. Some collective concerts were organized at that time with Club Moral and Pseudocode. Cassettes like Emissions 1 (1981) or Gomtrie d'un assassinat (1982) were released on their own label, some others in collaboration with Danny Devos (Club Moral) or Jerry WX (2Tracks, Digital Dance). EB001 was released by Club Moral in 1986, a few years after the facts. The two bonus tracks (only on CD) Sollicitation Extérieure and Psychosomatique are extracted from 4 IN 1, a cassette released in 1982 by Grafika Airlines, Brussels, including works by Pseudocode, Human Flesh and Mécanique Végétale.
