He's singing about HEEEEEYYYY YAAAAAAAAAAAAAAAA FOOOOOOOOORCESSSSSSSSSSI don't think I've ever heard anything by Susumu Hirasawa that I didn't love, and I have no idea what the fuck he's singing about.
I was listening to this and thinking "damn why do I feel like I've heard this" and then I looked up their discography. They fucking did the score to Akira! No wonder the choruses sounded familiar - I've seen that movie like 5 times.Just took out this old album Spellbinding Singings from Yamato by this mysterious and amazing group Geinoh Yamashirogumi. The sound is stunningly good: listening with great headphones and you'd swear you have demons inside your skull. Here is the last track on this album "Yamashiro Festivities - Tanukis". I don't read Japanese, but I figure that this song, an old lyrics set to new music, is about the Raccoon Dogs or Tanukis which according to Japanese folklore hold wild parties every night and are masters in shapeshifting -- and this music does shapeshift, a lot.
