For over forty years, with his sound poetry   revue 
OU (1964-1974), then through his participation in various international   
sound poetry festivals, through his personal experience in the   experimental studios of radio stations in Köln, Paris, Australia, Canada or   Sweden and in his concert/performances throughout Europe, Henri   Chopin  (1922-2008) has consistently and unceasingly opened the ways to unexplored   spaces beyond all known languages. Thanks to the systematic use of   microphones, amplifiers, tape recorders, editing and mixing consoles, he   has given a voice to realms beyond modern or experimental music,   beyond any note system and headed for spaces without norms, categories,   definitions or limits: spaces of permanent metamorphosis. 
But despite   misleading appearances, Henri Chopin is not merely doing a new kind of   music; he is not just a consequence of 
Pierre Schaeffer's concrete music principles and 
Pierre Henry's experiments in the   fifties. Henri Chopin is an individual (in Stirner's sense: the ego and its own) who has always resisted absurd attempts to   reduce him to part of a movement, a school, an academism; what one   perceives are Henry Chopin's bio-psychical vibrations, that he himself constructed by electronically recording, then modifying,   amplifying and transforming the energies of his own body. This language   is beyond institutionalised language or indeed beyond any language, it   precedes all idioms (sound signs, playful energy signs like those of   whales and dolphins), it is a breath language, a soul language (the   language of anima), the unfettered respiration of the cosmic energies   we are, who belong neither to factions nor clans. The energy of live   beings, whose individuality is irreducible, and impossible to break   down. Solitary and strange cosmic creatures, mysterious yet   showing solidarity, resonating with all those who dared breach shackles and   rules, escape vile obedience, submission and compromise, reject   complacency and blind allegiance to traditional or experimental academism.   With Henri Chopin let go and bid farewell to all that: here's a plunge into the unknown, an exploration of the inside of voice, of   the other side of voice, a sort of submarine navigation, of potholing   into the unmapped tunnels and grottoes of the glottis,   oesophagus, stomach and lungs, the places where pneuma (breath) is formed. 
Henri Chopin uses electronic devices to explore the pneumatic body   relentlessly, but never gives way to the temptation of artificially   fiddling with noises. He remains a-live, energetic vibration of the   pulsating, cosmic soul.
