That has nothing to do with hardness. What is hard when it comes to metal and what is not? Basically, this is nonsense. Someone to listen only Soul or Jazz, gets in Iron Maiden or Judas Priest headache because it distorts incredible for him and sounds loud (or, if you hard). That's all a matter of your own feeling.
Darkness, however, can be interpreted. And that has previously and afterwards anyway made no album the metal scene more. (And there were then already one or two blockbusters, such as the 'Seven Churches' Possessed). That's why I can even understand that some marvel, why just the black mark is so loved.
Well, that is because it was precisely at that time still too small or not yet present today and knows nothing else than the completely verwursteten Remaster versions. I do not know who at the time was sitting there in the new editions of the first three LP's early 1990's at the controls. Was it Quorthon personally? Can I do not think, because then he must have been completely filled - and I understand that it was more of the ascetic type.
Despite the 5 star, with whom this milestone is mE still undervalued (the first three Bathory albums are basically not evaluated because a genre has been created), I can not guarantee buy recommendation for the CD version or the remastered LP's. Those willing to enjoy the first three Bathory albums in full splendor, must now unfortunately come out of his pocket. Package around 50-100 per LP (yes on the state) are not uncommon.
But it is worth it. This is not voodoo slobbering, the difference hears every layman while diving.
One should not forget that those jewels constantly increased in value.
It is advantageous, of course, if you are still in possession of LPs.
