Four full flutes
Here is the complete CD catalog of this superior NYC composers collective label (aka Experimental Intermedia); although pretty low-profile, there are some amazing releases on this label in the spirit of long, droned tones and advanced new music composition. Don't let the title to this Niblock thing throw you off -- this is massive trance music and a key work in the unspecified field of "pure sound". "...adjacent tones beat violently against one another while clouds of harmonics hover above the wavering drone. When the piece ends, it takes the listener a few moments to recover. This physiological experience, when the ossicles slow their vibrating and the membrane hairs come to a standstill, is probably the only aspect of the music not regulated by the score. The four pieces on this 80 minute CD are for multiple tracks of alto flutes, flutes, flutes and alto flutes, and bass flutes, performed by Peter Kotik, Susan Stenger, and Eberhard Blum.
