In the twilight days of the 1970s henry built a brainwave-conduction system which he placed on the head(s) of various individuals, feeding the resultant voltages into a giant synthesizer... the concept being that the composer of the music (in the case of this recording: roger lafosse) was the one to whom the transducers were affixed. hearing the music (inarguably henrys fiercest and most unrelenting bit of pure analog scree) its understandable that this process never sparked an auto-electroacoustic-composition movement. Originally issued in a beautiful silver/black foil-stamped sleeve (repreoduced wonderfully here) as part of the illustrious prospective 21˚siecle series on philips. mind-slaying and so incredibly aggressive for a record from 1970. The Sweet Sweet sounds of pure oscillators.
