here's an example... this is a description taken from that blog i mentioned where the dl had expired:
"Jean-Francois Laporte - Mantra [Metamkine, France, 2000]
Highest recommendation for experimental/drone music fans. Easily one of the top 5 drone excursions I've ever heard!
This cute 3" cd, released through Metamkine's esteemed 'Cinema Pour L'Oreille' series of electro-acoustics and musique concrete, contains one track, "Mantra", which opens with a trio of motors starting up and emitting a gentle purr. As these engines warm up and shift through various perfunctory cycles, a wide spectrum of metallic vibrations slowly spins through the stereo field. While it would be nice to believe that these movements coincide with a Zamboni circling a really nice binaural microphone, it's more likely that Laporte exercised his artistic license with a judicious use of crossfading and stereo panning upon his field recordings. As the disc draws near its end, it sounds as if a screw or bolt is loosened by the vibrations and two pieces of metal begin a clamorous bell-ringing arrhythmia. When these motors finally are shut down, those pieces of metal still resonate for a beautifully sustained coda."
it goes on [but the next bit isnt as interesting]...
