Motörhead are a British heavy metal band formed in London, UK in 1975 by bassist, singer and songwriter Ian Fraser Kilmister, known mostly by his stage name Lemmy, who has remained the sole constant member. The band pre-dated, but are sometimes regarded as part of, the New Wave of British Heavy Metal, which re-energised heavy metal in the late 1970s and early 1980s. Motörhead is also regarded as, with Judas Priest and Accept, one of the first Speed Metal bands.
