This is something I’ve thought a lot about this past few years and I struggle to articulate exactly what it is that appeals to me about these genres of music.
I’ve always had a fascination with dark and macabre things since an early age I think so it was only natural I eventually discovered music of this nature.
I have extreme emotional attachment to many of my favourite black and death metal records. They resonate with me on a level that (most) other music doesn’t. There’s also a lot of nostalgic feelings attached to them - I’m often transported back to the specific time period or place where I discovered them and the memories that go with it.
Thinking about it there are 3 types of sounds I’m looking for with these genres:
There’s the mystical, emotionally charged, often more melodic stuff like The Chasm, Sacramentum, Dawn, At the Gates, Darkthrone, Burzum, Summoning, lots of Eastern European black metal, etc.
Then there’s the primal, filthy shit with an aesthetic I find appealing. Things like early Asphyx, early Bathory, Sarcofago, early Sepultura, Goatlord, Darkthrone (A Blaze in the Northern Sky), Demoncy, etc. The production in particular is often a big part of why I like this stuff. I can only describe it as being drenched in filth and rot.
Finally there’s the occult stuff. Things like Mortuary Drape, Root, Mystifier, Necromantia, Nastrond, Morbid Angel, etc.
I love extreme vocals when done well. While they’re obviously limited in range, for me they can convey a huge range of emotions. There’s pained and anguished, demented and revolting, disgust and hatred, haunting, demonic, etc. People who write them off as talentless are selling these vocalists short.
My starting points were Darkthrone’s - Transylvanian Hunger, Emperor’s - In the Nightside Eclipse and Morbid Angel’s Altars or Madness. I knew there was no going back after experiencing these.
I often wish I could be a teenager again and be in a place where I’m only just discovering this sort of music again. It was a time of awe and wonder and I doubt I’ll ever experience anything like it again. Of course, I’m still really excited when I discover an new album/band that really hits me. But I’m so accustomed to the general sound and aesthetic of extreme metal it just isn’t the same. I guess I envy the position you’re in - just beggining your exploration.
