If there's loads of material going by you don't notice the individual things quite so much. Also it really foregrounds the sonic dimensions like electronic ambient music, it's pushes all of that colour to the foreground so you hear little every atom of sound.
COIL would very much like to see the creation of a newsgroup for minimal musics. We enjoy a wide spectrum of such musics, from La Monte Young, Alvin Lucier, Arvo Part, Nurse With Wound's Solilique For Lilith,The Dream Syndicate (orig.concept not the newer group who plundered the name) to Synus, Earth and so on.and on and on. Some new so called ambient musics fall between genres and so between newsgroups: some of our own music has certainly been deeply inspired by and informed by such musics,from Partch to Subotnic.
