Speed metal is a sub-genre of heavy metal music originating in the late 1970's to mid 1980's that was the direct musical progenitor of power metal and thrash metal. Speed metal is characterized by staccato drumming, single-note riffing at fast tempos and complex guitar solos. Unlike thrash metal, speed metal uses melodical hooks. Lyrical themes of speed metal are those common for heavy metal. Early speed metal bands include Motorhead, Judas Priest, Venom, Anthrax, Megadeth, Rage, Helloween, Blind Guardian, Running Wild, Мастер, among others.
