John Darnielle describes Master of Reality in the voice of a fifteen-year-old boy being held in an adolescent psychiatric center in southern California in 1985. The narrator explains Black Sabbath like an emissary from an alien race describing his culture to his captors: passionately, patiently, and lovingly. This album has a genuinely remarkable historical status: as a touchstone for the directionless, and as a common coin for young men and women who felt shut out of the broader cultural economy.
