Motörhead was a British rock band formed in 1975 by bassist and frontman Lemmy Kilmister. Known for their fast, aggressive style that blended elements of rock, punk, and heavy metal, they became pioneers of the heavy metal genre, particularly the subgenre known as "speed metal." Motörhead's raw sound, energetic performances, and Lemmy's distinctive gravelly voice made them one of the most influential bands in rock history. Their 1977 hit “Ace of Spades” remains one of their most iconic songs, epitomizing their hard-hitting, no-frills style. Despite numerous lineup changes, Motörhead maintained a consistent presence in the rock world, with Lemmy as the unrelenting force driving the band forward until his death in 2015. Their legacy continues to inspire generations of rock musicians.
