Brume.

Brume is the name Christian Renou adopted in 1985 for what would become one of the French and Continental musique-concrete tradition's most prolific sustained career. The founding document is the cassette Frikture (1985, BRUME Rec., 50 copies), assembled from working pieces Renou had been working on across the prior working years; the gesture extends into the founding live position in June 1985 in a disused bus warehouse, an unauthorised performance the police closed at 23:00. The Bureau files the position at Tier I on the strength of the 40-year sustained life, the about 90 documents in the catalogue, the significant partnerships with the Continental experimental roster and the position's definitional weight in the French musique-concrete and noise tradition.

The method: Brume's position runs through the French musique-concrete tradition (the Pierre Schaeffer and GRM position) but operates from the cassette-culture and noise tradition rather than the academic-musique-concrete tradition the GRM and adjacent French positions mainly inhabited. The method is documented as dense, rapid-fire montage working composition, with deliberately wide working-source vein: location recordings, analogue and digital electronics, found-source material, voice, guitar, percussive surfaces, tape manipulation. The Bureau reads the method as distinct from the academic-musique-concrete tradition: Renou's position deploys the idiom through cassette-and-noise distribution rather than through the concert-and-broadcast tradition.

The cassette-period catalogue (about 1985–1999): Renou produced about forty-five whole Brume cassettes across the early life on the European, American and Japanese cassette-culture network. The early partners include the own BRUME Rec. imprint (the First release), Old Europa Cafe (the long-running Italian partner; Brume's Temporary Pigments 1989, The Sun 1990, Musique pour les Etres Humains 1992 and the catalogue items), Tonspur Tapes (the Continental partner Dachise later shared), Underground Productions, RR Productions, RRRecords (the American partner; Recycled 1990), ND (the American partner in the John Watermann tradition; Standard 1994) and the Continental and American cassette-culture network.

The first CD document is Xeros (1993, Korm Plastics / Staalplaat), the transition from the cassette format into the CD tradition. The Staalplaat partnership is significant: the partnership documents the Brume position's integration into the Staalplaat roster (Muslimgauze, Nurse With Wound, Rapoon, O Yuki Conjugate, Illusion of Safety, Aphasia and the Continental tradition).

The collaboration is Brume vs. Aphasia · Series One: Round One (1996), the partnership with Aphasia (Richard Johnson's electroacoustic sonic-collage position). The partnership is one of the 1990s French / British experimental tradition's documented collaborative documents; the partnership documents the partnership between the French musique-concrete tradition (Renou's position) and the British electroacoustic-and-noise tradition (Johnson's position). The later collaborative partners include Bastard Noise (Brainstorming 2003, Brainstorming II 2009), Troum (Dissolution 2004), Anemone Tube (Transference 2003, Auf Abwegen), Kommissar Hjuler und Frau, K2, TBC, Sudden Infant, La Nomenklatur and the experimental roster across the life.

The transition (2001–2008): Renou abandoned the Brume name in 2001 and operated under his own name (C. Renou) for the later seven working years. The C. Renou position is Fragments and Articulations (2002, Ground Fault), the position that documents the transition from the dark-ambient and post-industrial Brume manner into the later-developed experimental sound-art palette. The C. Renou catalogue extends through 7 Kisses (2003, EE Tapes), Ex-Voto (2007, Elsie and Jack), Gone With the Wound (2007, Taâlem) and the mode. The return to the Brume name occurred about 2008; the Brume catalogue has later sustained continuously through the present.

The retrospective is the Anthology 1979–2000 13 CD box-set (Waystyx, 2008), the document of the founding and cassette-period tradition. The Bureau reads the position as definitional for the Continental musique-concrete and noise tradition; the 13-CD scope of the retrospective document constitutes the position's most artefact. The continuing positions through the 2010s and 2020s include Ainsi soit-il! (2010, Rotorelief LP), Draft of Confusion (2010, Intransitive Recordings), The Rusty Seeds (2019, EE Tapes LP) and La Violence du Néant (2023, EE Tapes CD).

The Bureau's editorial reading: Brume is filed at Tier I as Christian Renou's long-running French musique-concrete and sound-collage position. The 40-year sustained life, the about 90 documents in the catalogue, the partnerships across the Staalplaat / Old Europa Cafe / ND / Waystyx / Intransitive / EE Tapes / Auf Abwegen / Rotorelief / Elsie and Jack network, the collaborative partnerships with Aphasia, Bastard Noise, Troum, Anemone Tube and the experimental roster, and the position's definitional weight in the French musique-concrete and noise tradition constitute the significance the Bureau files. The position's editorial stance on classification is documented (I reject the butt of all these stupid labels) but the Bureau notes the vein is in fact identifiable across the catalogue tradition.
