Black Sabbath's 40 Greatest Songs: 10-1 - Black Sabbath's best songs: the 40 greatest
During the recording of Master Of Reality, Tony Iommi took the decision to tune his guitar down three semi-tones in order to give Sabbath a weightier, heavier sound. That decision would eventually birth the entire stoner rock and grunge movements. One of Iommi’s favourite Ozzy-era recordings, Into The Void’s lumbering riffs and tempo changes gave it a jarring, dislocated feel. That Soundgarden, Kyuss, Melvins and Monster Magnet would all later cover the track is a testament to its influence and enduring power.
