Master of Reality

Master of Reality includes classics such as 'Sweet Leaf,' 'Children of the Grave,' 'Into the Void,' 'Lord of This World,' and 'Solitude.' The album's combination of heavy riffs and dark themes solidified Black Sabbath's signature sound.

Yes, guitarist Tony Iommi down-tuned his guitar three semitones to C# on Master of Reality, partly to reduce tension on his injured fingertips from a factory accident. This created a heavier, sludgier tone that became a defining characteristic of doom metal and influenced countless heavy bands.

Master of Reality is widely regarded as a foundational album for doom metal and stoner rock, thanks to its slow, down-tuned riffs and dark, ominous atmosphere. Its influence can be heard in bands ranging from Sleep and Electric Wizard to Kyuss and Saint Vitus.

'Sweet Leaf' is an ode to marijuana, opening with the sound of guitarist Tony Iommi coughing after taking a hit. The track is one of Black Sabbath's most recognizable songs and is considered an early anthem of stoner culture.
