37. Motorhead: ‘Ace of Spades’ - Desperados in tight denim and bullet belts, this is one of the most clichéd filthy metal covers of all time, with Lemmy and co. tracking through the desert like true cowboys from rock and roll hell. The truth paints a much less metal picture, however - the photo shoot took place on a pile of builder's sand in the middle of a busy London street. Tragically brilliant!
