BLACK SABBATH 'VOL. 4' LP (Limited Edition)

Black Sabbath could seemingly do no wrong by the time they delivered 1972’s aptly titled Vol. 4 — the Birmingham trailblazers’ fourth full-length release in just over two years. Indeed, the U.K. quartet were quickly defining and redefining exactly what heavy metal could be, filling the record with sludge-swung heaviness (“Under the Sun”), Satanically psychedelic freakouts (“St. Vitus Dance”) and even a tender piano ballad (“Changes”). Sabbath may have been “Snow Blind” as they soared through the Seventies, but Vol. 4 remains a visionary early metal masterpiece.
