Motörhead are an iconic English heavy metal band that started in 1975 by bassist, singer and songwriter Lemmy Kilmister. His aim was that the band would be "the dirtiest rock n' roll band in the world." They had an incredible loud and fast style, which led them to create speed metal and crash metal. This was captured on ‘No Sleep ‘Till Hammersmith’ in 1981 that was recorded live in London during their ‘Ace of Spades Tour’, which is recognized as one of the best works of the era.
