Each corner is a ten-point rating. The further out, the higher.

The difference, by ear

Black metal is growled or screamed where Bay Area thrash is shouted, and swings further either way: 160 to 280 bpm against 180 to 240. To hear the difference, play Metallica next to Bathory. They share a root in heavy metal, and black metal came first, by a year.

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.
