Where it sits
In short
Tremolo picking, blast beats, shrieked vocals and deliberately cold production. More an aesthetic than a technique - atmosphere matters more than clean sound.
How it sounds
- Tremolo picking on open fifth voicings, with vocals in the high register.
- Deliberately thin, cold production - the missing bass is an aesthetic choice, not an accident.
- Fast blast beats, drums often mixed back, atmosphere placed above technique.
Key acts
- Bathory
- Mayhem
- Darkthrone
- Emperor
Start here
The pickDarkthrone - A Blaze in the Northern Sky. The production is intentional, not a flaw.
