In short

Electric blues played louder, longer and with improvised solos. The direct bridge between Muddy Waters and Black Sabbath.

How it sounds

  • Pentatonic scales and long bends inherited straight from B.B. King and Buddy Guy.
  • Amplifiers driven into natural saturation - the distortion comes from volume, not a pedal.
  • Long songs with room for live improvisation.

Key acts

  • Cream
  • The Yardbirds
  • Jimi Hendrix
  • Fleetwood Mac

Where it sits

Heavy metalBlack 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.
