You really can't call this music in the traditional sense as he is employing a series of tones, pitch changes, long drawn out effects and so forth. The CD is split in ninety-nine separate short sound entities that can be strung together into different forms with the Random feature. It's purpose is to serve either as late night background sounds for when you are furiously slaving away at a paper or perhaps wanting to mellow out entirely.
Lull is possibly the purest form of definition ambience and for soundscape afficianados exclusively.
