After all the bands are always there, it's the genres that come and go. For instance black sabbath wasn't doom metal when they started, the genre came later. And so forth

There was a time when all avant garde black metal bands were either mimicing Deathspell Omega or Arcturus, good thing that stopped. But even if that sorta thing happened, there is always a new term to describe the weird stuff.

I hope avantgarde / experimental bands never start sounding the same, they're the best thing the metal scene has to offer

well nowadays, a nu metal band is a band that sounds like other band that has already the lavel, like alternative. They are recursive genres. But when Limp Bizkit first coined the term the intention was that

Plus I don't think Nu Metal is just metal with rap influences since bands like Slipknot and Static-X doesn't have those influences in them

first prog, then alternative, and now we have "avantgarde" or "experimental" to describe different stuff. later, those bands are gonna start sounding all the same again so we're gonna have a new term

uh You know when they call bands like Slipknot Alternative I thought they meant a different route of heavy. Like a mix of heavy and soft with some melody.
