The difference, in figures
Black metal is far heavier (+5), clearly faster (+4) and clearly less melodic (−3) than Progressive rock. It emerged in 1982, 14 years after Progressive rock in 1968. They sit on opposite branches of the tree and share no common ancestor.
Progressive rock
Where it sits
In short
Rock with classical ambitions: odd meters, twenty-minute suites, mellotron. The direct foundation of progressive metal.
How it sounds
- Odd meters - 7/8, 5/4, 13/8 - used routinely rather than as an effect.
- Mellotron, Hammond organ, Moog and later polyphonic synthesizers.
- Long suites, concept albums, sometimes a single piece per side of vinyl.
Key acts
- King Crimson
- Yes
- Genesis
- Rush

Where it sits
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.
