Secondly, are you aware that Darkthrone's first album is death metal? They're hardly the best example of pure black metal.
Since the Quorthon/Venom thing was mentioned: I believe Quorthon simply because it's such a ridiculous story. Who would do that? "yeah, so I'll blatantly rip off their sound, write some songs with the same names, some shit like that..." I also find that in fact Bathory drew more on what Quorthon cited - Oi punk - and Venom on whatever they were drawing on and while Black Metal and Bathory sound pretty similar if you listen to the riffs they're in fact not actually that similar.
But to me it doesn't matter, because Bathory's best stuff was after Bathory.
Basically, my point is that I think both parties would agree that a new band which emerged with a sound like Venom's or Celtic Frost's wouldn't be referred to as black metal. We're just bandying about what are essentially two different meanings of the same term without any genuine disagreement.
What I meant was that what we call a ruby is a ruby and is clearly distinct from other things scientifically. The name of it is unimportant. One can prove that what we call a ruby is distinct from a spinel. Black Metal, or any genre, has no set essence or nature in that sense. Lacking that, I think using historical examples as a basis for labeling is as good a reason as any.
This is pretty much what I meant. I put science in there to make sure people understood I meant the differentiation between the actual things ruby and spinel and the words, but obviously that backfired.EDIT 2: I think I know what you're saying, possibly because I missed the sentence "The name of it is unimportant" OR because your way of thinking is incredibly linear (no offense of course). Anyway, I believe what you're saying is that UNLIKE the actual ruby (its intrinsic physical form, that is) black metal has actually changed over time (along with what it is called, though to a lesser degree than the sound itself has, for obvious reasons).
Rubies have not changed, just what we call them. Black metal actually HAS evolved and changed dramatically in a very short period of time. Makes more sense this way. I don't think you had to add the whole science is right thing into it because I think it bogged down your point, for me anyway.
But no one ever referred to country music as black metal
