Motörhead were an English rock band formed in London in 1975 by bassist and lead vocalist Lemmy Kilmister, guitarist Larry Wallis and drummer Lucas Fox. Lemmy was also the primary songwriter and only constant member. 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 drummer Phil "Philthy Animal" Taylor and guitarist "Fast" Eddie Clarke.

The new wave of British heavy metal was a nationwide musical movement that started in England in the mid-1970s and achieved international attention by the early 1980s. Editor Alan Lewis coined the term for an article by Geoff Barton in a May 1979 issue of the British music newspaper Sounds to describe the emergence of new heavy metal bands in the mid to late 1970s, during the period of punk rock's decline and the dominance of new wave music.
