Dan Deacon - A Green Cobra Is Awesome Vs. The Sun
"This is a piece for several droning sine waves.
I wrote it in 2002 using reason.
Its best played on nice speakers, in a quite room, at a loud volume while the listener(s) walk around the space, hearing how the sine waves react/sound difference depending on where they stand and the direction of their ears. shaking your head from left to right also changes how you hear the sound. if its loud, different overtones will come out the closer you stand to a wall."
