Black Sabbath invented heavy metal. Formed in Birmingham in 1968, the band's raw, distorted guitars, ponderous rhythms, and apocalyptic lyrics created a template that defined the genre for decades. Their influence extends far beyond metal into rock pedagogy, where their early work remains a masterclass in groove and dynamics.
Tony Martin's bass lines provided the low-end foundation that made Sabbath's sound monumental. His playing combined simple, memorable riffs with surprising sophistication, proving that heavy music didn't require technical excess to hit hard.
