The demos were recorded at Rockfield Studios in Wales and Monaco Studios, and they capture the band in a raw, transitional state. Unlike the polished (though still heavy) final production of the album, the demos strip away the studio gloss and reveal the sheer volume of the riffs. “The Fallen” – A fast, punk-influenced track (by

4. Unreleased & Rarity Demos

  • “The Fallen” – A fast, punk-influenced track (by Sabbath standards) with a sardonic Dio vocal about corrupt politicians. Left off Dehumanizer entirely.
  • “Lost Forever” – A moody, acoustic-driven verse with an explosive electric chorus. Later reworked by Iommi for his 2000 solo album Iommi (featuring Peter Steele).
  • “Buried in the Backyard” – Dark, narrative lyrics about a serial killer. Only exists as a rough rehearsal recording; never officially released.
  • “No Stranger to the Dark” – A slow, almost doom-metal epic. Dio later rewrote the lyrics as “Evil Eyes” for his solo album Strange Highways (1994), but the Sabbath demo remains unreleased.

Significance

The demo is a different beast entirely. It opens with Iommi’s raw, unaccompanied riff—slower, more lurching, like a dying machine taking its last steps. The tempo is slightly slower than the final, giving it an almost funeral-doom weight. Appice’s drums are looser, with fills that feel desperate rather than calculated. When Dio enters with “Here is the voice of the computer god,” he’s not declaiming from a mountaintop; he’s muttering from a bunker. The bridge section, where the song breaks down, is extended in the demo, allowing Iommi to solo over a single, hypnotic bass note. This section is pure Sabbath Bloody Sabbath era improvisation—dangerous, unhinged. The final version tightens it up, losing the chaos but also the soul.
