Black Sabbath Dehumanizer Demos -

Listen to the rare rehearsal tapes featuring Cozy Powell and early versions of the album's tracks:

In late 1990 and throughout 1991, this resurrected beast retreated to Rich Bitch Studios in Birmingham, England, and later to various rehearsal spaces, to write. The resulting demo tapes, which have circulated among tape-traders and bootleg collectors for decades, document a band shedding the polished, melodic rock of the late 80s in favor of something sinister, contemporary, and devastatingly heavy.

For drum enthusiasts, hearing Cozy Powell tackle material that would eventually be defined by Vinny Appice provides a fascinating "what-if" scenario for the album's legacy.

: Initial writing sessions took place at Rich Bitch Studios in Birmingham with legendary drummer Cozy Powell. These demos are highly prized by collectors because they feature Powell's powerhouse drumming on early versions of songs like "Computer God" and "Letters from Earth".

The band relocated to Rockfield Studios in Wales to re-record and refine the material with Appice.

Listening to these demos provides a staggering alternate history. Martin’s performance is phenomenal, delivering a more melodic, soaring power metal vibe to the tracks. Ultimately, Warner Bros. Records had funded the project specifically for a Dio reunion, and pressure from management forced Iommi and Dio to resolve their differences, leaving the Martin tapes as a fascinating historical footnote. 4.

The demo collections, particularly the Japanese 3-CD set, list several instrumental tracks (often noted as "Unreleased Instrumental #1-#5"). These are critical in understanding how Tony Iommi constructs his riffs. These sessions show Iommi experimenting with heavier, doom-laden structures that perhaps did not fit the more progressive direction Geezer Butler was bringing to the lyrical content. Why the Dehumanizer Demos Matter

Powell’s drumming style was inherently different from original Sabbath drummer Bill Ward or Vinny Appice. He brought a driving, thunderous rock groove to the table. The demos recorded with Powell showcase a version of Dehumanizer that felt more aligned with late-80s power metal than the doom-laden sludge the album eventually became.
