Black Sabbath

1968-2017

Birth of Metal

1970-1971

Inventing heavy metal through blues-rooted riffing and doom-laden atmospheres. Three albums in under two years that established the sonic vocabulary of heaviness itself.

Psychedelic Expansion

1972-1975

Growing sophistication, studio experimentation, and drug-fueled excess. The band pushed beyond simple riff-driven metal into progressive structures, orchestration, and synthesizers.
