For VK? I suppose you mean VK has a distinct harsh vocal they'd adhere to? I don't mean this in a bad way I'm just genuinely curious 😶. At any rate, I'll always adore his harsh vocals in earlier albums, but as far as later album goes I think his harsh vocals come from a place of finding a proper technique that could be less damaging? I also always tend to think that harsh vocals from earlier albums were just an accent, something to add color, where as later on it was more of a prominent sound he was going for and so it sounds different with practice and has improved in my opinion.
