Inspired Flight's "An Outlet" is an example of what I mean.
For the first few measures, a melody of 16 eighth notes is established in middle register (if I have it right: A E A E; A F G C; A E E- E; A F G C). Then, starting at 0:13, a repeated melody of 9 eighth notes is introduced in a higher register (F C A; F C A; D C A). Since 9 and 16 have no common factors, there are a lot of dynamics that arise during the theoretical 144 eighth notes that it takes for the two to reach a common repetition.
Although I didn't realize this kind of quasi-periodicity was happening until I attempted to transcribe it, it seems like a neat technique for creating texture. Does it have a name?
