Ace of Spades is the fourth studio album by the band Motörhead, released 8 November 1980.
By 1979, Motörhead had released two successful albums, Overkill and Bomber, and had gained a loyal fan following by constant touring and television appearances. Their ferocious, loud proto-thrash playing style appealed equally to punks and heavy metal fans.
In the 2011 book Overkill: The Untold Story of Motörhead, Joel McIver quotes vocalist and bassist Lemmy:
"..I like Iron Maiden and Saxon out of the new mob, and that's about it, really...We were too late for the first metal movement and early for the next one...Motörhead don't fit into any category, really. We're not straight heavy metal, because we're a rock 'n' roll band, which no-one knows how to market anymore.."
Like the song "Shoot You in the Back," the Ace of Spades artwork employs a classic wild west motif. It was the second of the band's studio albums to feature a depiction of them on the front cover, dressed as cowboys, in lieu of their mascot Snaggletooth. The 'Arizona desert-style' pictures used on the album sleeve and tour programme were taken during a photo session at a sandpit in Barnet.
