Master of Reality

Master of Reality is the third album by heavy metal band Black Sabbath, released in 1971 (see 1971 in music).On this album, guitarist Tony Iommi began de-tuning his guitar down three semi-tones (or one and a half steps, or C♯) to reduce tension in the strings, making it easier to play with his injured fingers. This led to a lower, sludgier sound that became the Master of Reality trademark.The lyrical themes include: drugs, solitude, war and theology. "After Forever" is credited lyrically to Iommi (the only Sabbath lyrics solely credited to him thus far) and is heavily Christian-themed.
