Where it sits

RockRock and roll

In short

Ground zero: twelve-bar blues sped up, piano hammered hard, lyrics about cars and girls. It made the electric guitar the defining instrument of the century.

How it sounds

  • Twelve-bar blues sped up, with piano pounded in eighths and saxophone where the guitar solo would later go.
  • The guitar plays short repeating riffs rather than long solos - Chuck Berry essentially wrote the vocabulary.
  • Mono production, one room, dance-hall energy.

Key acts

  • Chuck Berry
  • Little Richard
  • Elvis Presley
  • Bo Diddley

Start here

The pickChuck Berry - Johnny B. Goode. That opening riff is the DNA of the entire tree.

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.
