Darkthrone IS the definition of Black Metal.
Yes, but I'm sure you can tell, but by definition black metal I meant bands who intentionally fulfill every black metal aesthetic.
Obviously a band nowadays can make a black metal album, and record with even rawer production, grimmer corpse paint, and meet or exceed criteria for what the general consensus would agree makes the ideal black metal album...but does that make it any more authentic or 'black metal' than a band who actually helped develop and spawn the scene? No.
So yes, I agree with you and it would be almost ironic to suggest than any bands from today is any more black metal than Darkthrone.
