"This strange electronic opus furiously in the early 70s, comes from the famous collection "Prospective 21st Century" from Philips. Corticalart The (literally: the art of the cortex) is a device designed and developed by the researcher and musician Roger Lafosse, a pioneer of cultural action pre- custody, founder, director and host of the turbulent Sigma festival in Bordeaux. Corticalart The compound is a complex system designed to translate electrical brain waves into electronic sounds. The electrode system similar to that used in electro-encephalogram is set directly in contact with the scalp of Peter Henry. These electrodes pick up then three kinds of signals reflecting electrical activity characteristic of some areas of the cerebral cortex. Alpha waves on the back of the skull (state of relaxation, relaxation, rest), Beta waves on the front of the skull (alertness, attention, activity) and the signals of the edge Fact related to the activity of the eyeball. These electrical signals of very different low voltage generators are connected to seven of the electronic sounds, Pierre Henry had to intervene manually as improviations musical, with variations, various manipulations and amplification. Strange system where the performer is also the base material and sound compositions.

The nine titles on the disc are from live recordings made during the concerts at the Museum of Modern Art in the city of Paris between 15 and 21 February 1971 and showed the relevance of Pierre Henry 's event, the ceremonial and excess. Here, the remarks of Michel Chion on the first sessions of 1971 at the Museum of Modern Art in the City of Paris: "The first experience Corticalart leads many public at the Museum of Modern Art, in its free sessions. It shows a staggering Pierre Henry, concentrated , electrodes on the head, dark glasses over his eyes, into a wire cage and activate its apparatus. A television screen broadcasts the image of his face, tinted blue to Alpha waves, red for Beta waves, with intermediate shades. And they are great rhythmic improvisations, on a hot stream of sound and obstinate. " With

this disc UFO confusing and underrated 1970s, Peter Henry is among the pioneers in the field of music produced from human brain waves, just as Alvin Lucier (Music for Solo Performer - 1965) and the group of Richard Teitelbaum Musica Elettronica Viva (Spacecraft - 1967). A sinusoidal

music for droid (scientist!), Imaginative and amazing smelling blood, and excessive overheating of electronic sound generators. " Source Sonhors
