Motörhead were an English rock band formed in June 1975 by bassist, singer, and songwriter Ian "Lemmy" Kilmister, who was the sole constant member, guitarist Larry Wallis and drummer Lucas Fox. The band are often considered a precursor to the new wave of British heavy metal, which re-energised heavy metal in the late 1970s and early 1980s. Though several guitarists and drummers have played in Motörhead, most of their best-selling albums and singles feature the work of Phil "Philthy Animal" Taylor on drums and "Fast" Eddie Clarke on guitars.

Motörhead released 22 studio albums, 10 live recordings, 12 compilation albums, and five EPs over a career spanning 40 years. Usually a power trio, they had particular success in the early 1980s with several successful singles in the UK Top 40 chart. The albums Overkill, Bomber, Ace of Spades, and particularly the live album No Sleep 'til Hammersmith cemented Motörhead's reputation as a top-tier rock band. The band are ranked number 26 on VH1's 100 Greatest Artists of Hard Rock. As of 2016, they have sold more than 15 million albums worldwide.
