Okay, that crunkcore genre definitely wins over Pornogrind for being the worst weird sub genre. If I was forced to listen to that **** for an hour I'd probably literally puke.
Not really a sub genre, but here's some extreme metal band fronted by a dog. yes, I'm dead serious.
I also remember there being a band of another animal, I'm not sure which though. I think it was a parrot?
