Shouted. Barked or chanted, and you can still make out the words.

In short

Thrash slowed to a groove that hits you in the chest: syncopated riffs, mid-tempo drums, barked vocals.

How it sounds

  • Syncopated riffs with offbeat accents at mid tempo.
  • Down-tuned guitars with very thick tone and squealing pinch harmonics.
  • Barked, aggressive vocals with near-rhythmic phrasing.

Hear what that means

Loaded only when you press play — nothing reaches Google before that. Every second here is the uploader's own, read from the recording's tracklist.

The specifics

Tempo
90-140 bpm
Song length
3.5-5 min
Tuning
Drop D and lower, with the riffs written to sit in the pocket rather than to run — the tuning gives weight to a rhythm that is already the point.
Production
Dry, tight and percussive, with the guitars gated so the silences between chugs are silent. The snare is enormous and the whole record is mixed to hit.
Written about
Anger, Self-reliance, Politics, on the Brazilian side, Contempt for the scene

What each part is doing

  • Guitar Thrash riffs at half speed with a swing put back into them, using pinch harmonics as punctuation and leaving space where thrash would fill. The syncopation against the kick is the genre.
  • Bass Locked to the kick drum absolutely, which is what makes the groove feel like one instrument rather than three.
  • Drums Playing behind the beat with a heavy backbeat, and leaving gaps deliberately. This is the most rhythmically spacious drumming on the metal branch.
  • Vocals Shouted rather than growled or sung, phrased with the riff, and delivered in a register that a crowd can shout back.

What it isn't

That it is simplified thrash. Removing notes is the hard part: a thrash riff hides behind speed, and a groove riff is exposed — every hit is audible, the timing has to be exact against a deliberately behind-the-beat drummer, and the whole effect collapses if the syncopation is even slightly off. It is a genre about the placement of a small number of notes, which is why so few bands have done it well.

Told apart from

  • Thrash metal Groove metal is thrash at half speed with a swing in it. Same riffs, opposite relationship to the beat, and far more space.
  • Nu metal Both are groove-first and down-tuned. Nu metal takes its rhythm from hip-hop and adds turntables; groove metal takes its from thrash and keeps the solo.
  • Metalcore Metalcore's breakdown does the same job as a groove riff and arrives from hardcore rather than from thrash — and it is a section rather than the whole song.
  • Sludge metal Sludge is slower still, screamed, and dissonant. Groove metal is tight and shouted where sludge is loose and shredded.

The genres this one is most often mistaken for. Written, not derived.

History

Pantera abandoned glam metal and released an album in 1990 that redefined heaviness: slower than thrash, but far more crushing. Sepultura went the same way with Brazilian percussion, Machine Head with hardcore influences. The genre dominated the 1990s and set the stage for nu metal.
