  • DJ scratching or samples built into the arrangement.

Where it sits

Heavy metal › Black metal

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.
