Motörhead, originally called Bastard, is a long-lived and iconic heavy metal band from England formed in 1975 by bassist, singer and songwriter Lemmy Kilmister (real name Ian Kilmister). They are widely recognized as progenitors of thrash metal, a fusion of heavy metal and what was soon to become hardcore punk. Consequently they influenced countless rock, punk rock, and heavy metal bands that followed. Usually a power trio, Motörhead had particular success in the early 1980s with several successful singles in the UK Top 40 chart. The albums Overkill, its follow on, Bomber, Ace of Spades, and particularly No Sleep 'til Hammersmith, cemented Motörhead's reputation as one of the foremost english heavy metal groups. More recent exposure has included providing wrestler Triple H's entrance music, and performing live at WrestleMania events; and in 2004, contributing the song, "You Better Swim", to the soundtrack of The SpongeBob SquarePants Movie. In 2005 the band received their first Grammy.

While Motörhead are typically classified as heavy metal, speed metal or thrash metal (and often regarded as a foundational influence on the latter two styles); Lemmy dislikes such labels, preferring to describe the band's music simply as "rock and roll". Motörhead's approach has remained the same over the band's career, preferring to play what they enjoy and do best, their like for the early rock and roll is reflected in some of their occasional cover songs. Motörhead's lyrics typically cover such topics as war, good versus evil, abuse of power, promiscuous sex, substance abuse, and "life on the road".

The band's distinctive fanged face logo (known as Snaggletooth B. Motörhead, A.K.A Warpig) was created by artist Joe Petagno in 1977 for the cover of the Motörhead album and has appeared in many variations on covers of ensuing albums.
