Stoner Rock is a subgenre of rock music that combines elements from heavy metal, psychedelic rock, and blues. It is characterized by heavy, distorted guitars, a strong rhythm, and often repetitive staccato riffs. The compositions usually include long, instrumental arrangements with a focus on deep, aligned grooves. The vocals can range from atmospheric to more dynamic and intense. The genre became popular in the 1990s, with bands such as Kyuss and Fu Manchu making it known.
