Grunge is a form of alternative rock music from Washington that mixes elements of punk rock, heavy metal and 1970s hard rock. This style of music is most often played at a midtempo and usually features sludgy guitar distortion, raspy vocals and angsty lyrics. Grunge was pioneered in the 1980s and popularized in the early 1990s with the success of Alice in Chains, Pearl Jam and Nirvana.

Groove metal (also known as post-thrash or power groove) is a derivative form of thrash metal that is played at a moderate pace and places a greater emphasis on 'groove' and syncopation. This style was popularized in the early 1990s by the bands Prong and Pantera.
