Groove Metal / Post-Thrash
Located in 1 route
A mid-tempo, riff-forward offshoot of thrash that trades blur-speed for swing and weight: down-tuned, syncopated palm-muted riffs locked to a heavily accented snare, frequent half-time breakdowns and pinch-harmonic squeals, and a deliberate bounce in the 90-140 BPM range. Vocals are mostly a barked, shouted mid-range rasp rather than melody or full death growl, riding on top of a thick, scooped-mid guitar tone and prominent, percussive bass. The mood is muscular and aggressive but groove-locked, built for the pit's stomp rather than the gallop, with tight stop-start dynamics and chugging open-string lows.
History
Groove metal/post-thrash crystallized when thrash's first wave hit a wall around 1990 and bands chose weight and swing over raw velocity. New Orleans' Exhorder (Slaughter in the Vatican, 1990) and Pantera's reinvention on Cowboys from Hell (1990) and Vulgar Display of Power (1992) drew the template; Sepultura's Chaos A.D. (1993) and Roots (1996) added tribal percussion and tuned-down churn. Roadrunner Records became the hub, breaking Machine Head's Burn My Eyes (1994) and later White Zombie and Fear Factory. The style folded into the New Wave of American Heavy Metal via Lamb of God, DevilDriver, and Chimaira in the 2000s, and remains the dominant riff language of modern mainstream metal.
