Not only just Black metal, but also thrash.No, popularity doesn't necessarily correspond with influence. For instance, Venom never experienced much commercial success at all; but that didn't stop them from accidentally coining the term "black metal" and being one of the biggest influences on black metal bands ever.
Influencing the sounds of other bands is essentially popularity, maybe not with fans but with the bands. NEXT!
Yeah, it is. "LOL, Venom did that so we are going to do that too but slightly different, LOL."
That is popularity no matter how you slice it.
So we have to go with the band in question having an effect ON OTHER BANDS and what they do rather than the musical quality of the band itself for the definition of classic? Lame.
Romans were pagans.
? I am not supporting either commercial success or popularity.
Here is an idea then if the bands that followed them were indeed far better: call those follow bands classics. Why listen to a "classic" that is nothing but poor musicianship? Why even call it a classic if such is the case.
