There is a compelling argument to be made that the Dehumanizer demos represent the purest distillation of the Dio-era Sabbath sound. The Heaven and Hell album, for all its brilliance, still carried traces of late-70s arena rock. Dehumanizer was supposed to be the band’s response to the early 90s—darker, heavier, more cynical. The demos deliver that promise without compromise. The final album, while excellent, sands down some of those jagged edges for the sake of listenability.
But Bill Ward was struggling. Bullied by Ozzy’s then-manager/wife Sharon Osbourne and disenfranchised with the music industry’s pressure, Ward’s participation was fraught. He played on the album, but the demo sessions reveal a band that was already fracturing. In fact, Dehumanizer is famously the last full studio album with the original four until 2013’s 13 —a gap of 21 years.

This lineup had actually begun writing material for the next album. There is a compelling argument to be made
The primary and most voluminous part of the "Complete Dehumanizer Sessions" comes from the initial 1991 writing and recording sessions. The lineup for these sessions was . Powell had worked with Iommi before but was a surprise choice for Sabbath.
The initial rehearsal sessions took place at Rich Bitch Studios in Birmingham in 1991. Crucially, Cozy Powell was still the drummer during these early sessions. This brief intersection of musical titans—Iommi, Butler, Dio, and Powell—spawned the first batch of Dehumanizer demos, which remain some of the most sought-after recordings in Sabbath lore.
