Black Sabbath Dehumanizer Demos
Listening to the Richfield tapes reveals a drastically different vibe from the finalized album. Powell’s drumming style was orchestral, bombastic, and deeply rooted in classic hard rock. Songs like "Computer God"—which actually originated from a track Geezer Butler had been working on with his solo outfit, The Geezer Butler Band—had a more driving, traditional heavy metal gallop in these sessions.
| Demo Title | Album Equivalent | Notable Differences | |------------|----------------|----------------------| | “Computer God” | Same | Alternate vocal melody in the verses; longer atmospheric intro with different synth pad; raw drum mix with less gated reverb. | | “After All (The Dead)” | Same | Faster tempo; Dio uses a lower-register verse melody; Iommi’s riff has a slightly different accent pattern; Cozy Powell’s fills are more chaotic. | | “TV Crimes” | Same | Alternative lyrics in the second verse (“preacher on the screen / selling holy gasoline” instead of final version); guitar solo has a wah-wah effect not present on album. | | “Letters from Earth” | Unreleased until 2011 | A fully realized outtake not on original album. Features a crushing mid-tempo Iommi riff, lyrics about environmental collapse. Later re-recorded (less effectively) by Iommi with Glenn Hughes. | | “Time Machine” | Version used in Wayne’s World (1992) | The demo is closer to the film’s harder, faster mix than the album’s slightly more subdued take. Different drum pattern in the chorus. | | “Sins of the Father” | Master of Insanity (final title) | Original title and lyric concept about Catholic Church abuse (later changed to a more general “inner demon” theme). Heavier, slower guitar tone. | | “I” | Same | Demo features an extended, spoken-word intro by Dio (“I am the end of the world / I am the fist that crushes your faith…”) cut from final album. |
The demos were cut quickly, often live in the studio, to capture the skeleton of songs before overdubs, vocal layering, and the sterile sheen of 1990s production took over. black sabbath dehumanizer demos
The earliest Dehumanizer demos began in 1991 at Rich Bitch Studios in Birmingham, England. What makes these early tracking sessions incredibly significant to collectors is the presence of legendary drummer Cozy Powell.

The Rockfield demos capture this transition beautifully. Iommi tuned his guitar down to low drops, and Butler’s bass distortion was cranked to monolithic levels. The demos from this era include rough, unpolished versions of:
