I wonder why they don't try to market Godzilla's? Maybe in slow motion aka "Chopped and Screwed" (photoshop masters, do it!)
If you slowed down Goji's roar, it'd probably sound like any number of Lustmord albums. But he's not a whale, so he can't be mystical new age material with rainbows and crystals in the cover art.
Eh, there might be a little bit of whale in Godzilla. "Gojira" was a combination of the words "kujira" ("whale") and "gorilla." I believe the original roar was created by playing around with a big stringed instrument in a recording studio. I liked that whale monster design, too, it fit the "parasite" thing and it was a neat looking design. I'm happier with what we got, though. Looked like a naked bat.
