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

The difference, by ear

Black metal is growled or screamed where alternative rock is sung cleanly, and much faster: 160 to 280 bpm against 100 to 150. Songs run longer in black metal: usually 4 to 9 minutes, against 3 to 5 minutes in alternative rock. To hear the difference, play R.E.M. next to Bathory. Alternative rock comes from the rock side of the tree and black metal from the metal side, and black metal came first, by three years.

Where it sits

Rock › Alternative rock

In short

An umbrella for everything that grew outside commercial radio and then conquered it. Defined originally by the college-radio network, not by any one sound.

How it sounds

  • No single sound - originally defined by the distribution channel rather than by style.
  • What the bands share: less glossy production and less predictable structures than radio rock.
  • Quiet-loud dynamics, popularised by the Pixies and copied by everyone after 1991.

Key acts

  • R.E.M.
  • Pixies
  • Nirvana
  • Radiohead

The pickPixies - Doolittle. Cobain admitted he was simply trying to write a Pixies song.

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.
