Some groove metal bands such as Machine Head and Fear Factory experimented with nu metal briefly during the late 1990s and early 2000s. Some groove metal bands had influence on nu metal bands and some bands took many elements of groove metal, including the use of low, down-tuned guitars, groovy riffs and lyrical attitudes. Template:Original research Template:Unreferenced Nu metal Groove metal typically follows in a medium tempo, but can vary from band to band or song to song. Uncommon time signatures and polyrhythms are typical for some bands generally these bands put heavy emphasis on the changing beat. Groove metal drums typically use double-bass drumming, with emphasis on using the double bass drum in waves, rather than rapid fire double bass and blast beats used in the extreme metal styles. Vocals usually consist of thrash metal-styled shouts, hardcore-styled barks, and clean singing. Like most other heavy metal bass styles, groove metal bass lines typically follow the rhythm guitar riffs but are sometimes used as introduction to a guitar riff or as intermezzi when the guitar riffs are de-emphasized. Solid state amplifiers using transistors are commonly used to gain this asymmetrical harmonic clipping sound, although tube amps are used sometimes as well. The tone is typically described as thick and mid-scooped down with boosted bass and trebles, usually under a harsh distortion. Guitarists generally play low syncopated power chord patterns and mid-paced guitar solos, and occasionally use most heavy palm muting.
Groove metal bands tend to play mid-tempo thrash riffs focusing on a hard heaviness and groovy syncopation.

Groove metal is a blend of several genres from the 1980s, including traditional heavy metal, hardcore punk, crossover hardcore- heavy metal (sometimes called crossover thrash), thrash metal, and sludge metal. Groove metal, often associated with neo-thrash/ post-thrash and power groove, is a term sometimes used to describe an derivative subgenre of thrash metal, biker metal, heavy metal and death metal which took its current form during the early 1990s.
