I had in mind a maze like multi-dimensional library when starting this track. This was like the conflagration of a gigantic steampunk clockwork like building, with staircases that loop unto themselves like in an Escher painting, with rooms full of bookshelves that cross dimensions (a la Interestellar), and the occasional orangutan that goes "ook". Maybe it rearranges itself, like in the movie Dark City, or curves into itself a la Inception. Anything that speaks of structures that bend and suggest that there is something going on that we don't really get.
For that, I mixed traditional elements to give that mechanical vibe, between pianos, brass, stand up bass, and some arps that give a good structure. I also went for these strange sineous chromatic piano lines that don't seem to go anywhere. I did not have good "ook" samples but elephants can do surprising good job!
