Given who is on the poster behind you, given the following King Gizzard songs a chance: Dragon Han-Tyumi and the Murder of the Universe Robot Stop Rattlesnake
You're pretty much right that every album has its own story. Nonagon Infinity doesn't really have a linear story due to being an "infinite album" where every track transitions into the next and the last transitions into the first, essentially letting any track be the track you start the album with. The album does have lots of apocalypse imagery as well as a search for infinite youth or something. I haven't read too much about the lore of their albums, I just like the music. I know crocodiles and(/or) alligators are important to their stories though, and they write about the environment a lot. Glad you liked the song!
