Master of Reality

First released1971

Master of Reality was recorded at Island Records' studios in London during the summer of 1971, following the massive commercial success of Paranoid. The album was produced by the band themselves with engineer Tom Allom overseeing the technical aspects of the recording process. The sessions were notable for the band's experimentation with tuning down their guitars, particularly on tracks like "Sweet Leaf," which created a heavier, more sludgy sound that became influential in heavy metal production. The album was completed relatively quickly, reflecting the band's confidence and momentum at the height of their early creative period. Master of Reality was released in July 1971 and has since been recognized as a landmark in heavy metal and doom metal development.
