I still feel like there's several subdivisions you can make within Raccoon People World, personally.
There's the whole ''Dude, we love eroguro/the Showa & Taisho era/Terayama Shuji/old uniforms & we have five buckets of white paint left over - let's start a band''-variety that people already talked about ITT which pretty much covers all those bands like Guruguru Eigakan, Kalavinka, Inugami Circus-Dan, Strawberry Song Orchestra etc. Usually they go for more of a straightforward rock and/or kayoukyoku-influenced sound
Secondly, there's the subset of dudes who may or may not at least partially fulfill the criteria for the previous category as well, but who also set themselves apart by being influenced by that good old 80s Nagomu Records stuff & other new wave/zolo stuff from that time period. Here's where you have the kinda 'bleep bloop' stuff like Eiji w/ his million projects, Sharaku with his, Muchi Muchi Anago and all that stuff. Usually these ones have some electronics added into the mix
Thirdly you have the ''I have no fucking idea how to classify this but i am physically incapable of listening to anything not vk-adjacent and i saw two of the members hanging out with other vk musicians once so uhh... angura i guess'' category
Finally, there's Elektel-Shiki
