"Pure" (1992) by Godflesh. What a crushing release. This is the band's strongest release in my opinion. They mold a perfect apocalyptic doom landscape. They sound akin to the strongest riffs from Saint Vitus and Black Sabbath...but they meld these riffs with a drum machine and hellish droning feedback, bludgeoning you slowly, slowly, repetitively into claustrophobia, fear, and paranoia. The only musician that comes even close to creating such bleak, alienating, and frightening sounds capes is the god of psych space metal Helios Creed. Through and through, "Pure" is monumental, thundering and dissonant. The perfect soundtrack to the apocalypse. Highly recommended.
