The demo sessions for Black Sabbath's 1992 album Dehumanizer
These aren’t historical artifacts. They are ghosts. And for the generation that has listened to Paranoid a thousand times, the Dehumanizer demos offer something precious: a chance to hear Black Sabbath discover their darkness all over again, in real time, with no safety net.

To understand the demos, one must understand the atmosphere. The 1992 sessions, produced by Reinhold Mack (Queen, Electric Light Orchestra), were notoriously difficult. Dio and Iommi clashed constantly. Dio wanted to modernize; Iommi wanted the core Sabbath doom. Geezer Butler, the band’s lyrical conscience, was battling personal demons.
