Friend of mine was in London and gave me another Doxy release, which seemed to be sold out from wholesale company, but I'd suspect still very much available (2010 release!) around.
Pierre Henry "Musique sans titre / Spatiodynamisme" LPEach side is very long. I'd assume we're talking around 30 mins per side? Or did it just feel like it? Nevertheless, this is perhaps noisiest and the most similar to contemporary noise works. Recorded back in 1954, based on recordings made of Nicolas Schöffer's sculpture. For more info of this father of cybernetic art :
http://en.wikipedia.org/wiki/Nicolas_SchöfferThis music if the b-side of LP was meant to be soundtrack for the tour of the sculpture starting in 1955. Liner notes says it was intended, but doesn't say was it actually used? We're talking 1955 exhibition of 50 meters tall building of metal, mirrors, light and sound what interacts with environment and the visitors. This sound is grating and scraping sounds of metal, clashing and clanging.. and all this edited together with certain precision. Often there is simple strong elements going, with very tasty echoes of the era. Sound effects grow while going further and further on recording, and eventually, even if you can say you do recognize this as Pierre Henry's touch and approach, if it would have been sent as promo tape to some noise label, they'd be probably like "sounds good. So you guys been listening some TNB lately?".
If you have hesitated should you give your little finger to some ages old academic artists, I can say this is among the safest to start. And now, when it is just released and decent priced, I would recommend to try find it.
