The opening salvo of Powerslave, faster and more frantic than Run to the Hills. Dave Murray drove his black 'Kossoff' Stratocaster — loaded with a hot DiMarzio Super Distortion humbucker — into a cranked Marshall, while Adrian Smith doubled the harmonized lines. Smith summed up the whole album's guitar sound himself: 'all I paired them with was a 100-watt Marshall and maybe a Tube Screamer.' Producer Martin Birch tracked it at Compass Point in the Bahamas. Standard tuning; the gallop is in the picking hand.
