punk never really did evolve, it's stayed the same, sure someone might claim they are different but it doesn't mean it. they are still the same 3 chord rock that it's ever been and you can easily trace it right back to the source of where it came from
I can refute that in one word, and I can use several words to do it:
Post-Hardcore, Screamo, Emotive HardCore, Post-Punk, Minimal Punk, Art Punk, Horror Punk, Hardcore, Crust, Oi!, Skate Punk, Garage Punk, etc. That doesn't even begin to address fusion genres.
NiN is an industrial band
No it isn't. And EBM is only considered a subgenre of Industrial do to some hilarious confusion that arose when Industrial practitioners (Mainly SPK) dropped what they were doing to make poppier music. If you listen to actual Industrial you'll realize it sounds
NOTHING like EBM.
