I like the upbeat sound of this. I do agree that the high-pitched instruments are a bit painful on the ear. I also had quite a hard time following the pulse, and sometimes it feels like there is no real meter at all. Reminds me a bit of Lethal Lava Land in M64, which also is more of a collection of sound-snippets that doesn't fully follow a meter. I am not really sure what your Pandora's Music Box is and how these "incremental recordings" contribute to them, but I am quite intrigued :)
