Stoner rock and stoner metal are interchangeable terms describing sub-genres of rock and metal music. Stoner rock is typically slow-to-mid tempo, low-tuned, and bass-heavy. It incorporates elements of psychedelic rock, blues-rock and doom metal into a more repetitive and riff-centred style. Other common traits include melodic vocals and 'retro' production. The genre emerged during the early 1990s and was pioneered by the Californian band Kyuss.
