This song is part from the album "The noise floor: a compendium of overdubbed memories", an ambient/post-rock/experimental album where the noise is used like any other instrument. This is the context of the album:
I've always thought that the mind works like the old cassette tapes. Every time you relive those memories that roam your head, the reality gets distorted a little more and the noise floor gets bigger. Over and over again, until only a deafening noise remains. These are my ghosts, this is my overdubbed tape.
