Fractal Music Machine is an ongoing experiment in fractal music by Erika Nesse, a Boston based musician and software developer.
Fractal music is based on the notion of self-similarity, of making smaller things the same as larger things on many scales in order to obtain an ordered complexity.
Detailed explanation here.
I have two albums out of purely fractal music: Let My Machine Talk to Me (2016) and What the Machine Replied (2015). On these albums each track is a single whole fractal, created with fractal software and minimal postprocessing.
There is also a frequently updated playlist of fractal music experiments on soundcloud: Fractal Music.
My youtube channel has several fractal music videos.
A simplified command line version in Python called "weaving beats" is also available here.
