Speed metal is a subgenre of heavy metal music characterized by its fast tempos, aggressive guitar riffs, and high-pitched vocals. It emerged in the early 1980s, drawing influences from both thrash metal and traditional heavy metal. Bands like Judas Priest and Motörhead played a significant role in shaping the sound, which often features intricate solos and powerful drumming. The genre is known for its energetic performances and technical musicianship. Speed metal often explores themes of fantasy, warfare, and rebellion, appealing to fans who enjoy intense and fast-paced music. Notable speed metal bands include Helloween and Gamma Ray, who helped popularize the style in the late 1980s.
