Music and animation blends greatly together with the same initial thinking as how the same initial 8s melody/animation can goes over and over again while changing at same time.
In the music and animation it's hard to know what came first and what came second but I'll actually divide it in 3 part (it's my own division and you may do more or less than this):
First the original melody and animation are very close to a 8s loop I can see the influence of Yoji Kuri and Yamamura Koji work: minimalists variations in term of sound and animation giving a strange loneliness vibe. Also I feel like the 8s second scene was at first 8 different scenes that were put together from the 8 people credited at the end.
Second a faster part sounding a little like Akira Fukube's Ostinata Ritmica introducing color is the heart of the animation and I'm not an expert so I don't know the name of what I saw relying mainly on perspectives like Mind Game (the scene of the running blue man can be find almost at the identical in the two).
Last part really dissonant (close to Krzysztof Penderecki works) let me dumbfounded: the drinking character wasn't here anymore and everything was chaotic unrestrained by the colour, the form, the logic.
In the end it's not really for everyone but if you want something original or if you want to work on the animation in the future it's a great finding (you can also check the reference I made here).
