Buried Alive Line up: Ronnie James Dio – vocals Tony Iommi – guitar Geezer Butler – bass Geoff Nicholls – keyboards Vinny Appice – drums Record Label / Year of Release: I.R.S. 1981 Notes: Dehumanizer is the sixteenth studio album by British heavy metal band Black Sabbath, released in June 1992. It was the first Black Sabbath studio album in over a decade to feature Ronnie James Dio on vocals and Vinny Appice on drums, and the first in nine years to feature original bassist Geezer Butler. Initial writing and demo sessions at Rich Bitch Studios in Birmingham featured drummer Cozy Powell; bootlegs of these sessions exist. The record was originally to be done with drummer Cozy Powell, then Black Sabbath's current drummer, but he was immobilized by a broken pelvic bone he had sustained in a horse riding accident. Dio initially wanted to replace Powell with Simon Wright, from AC/DC and his own band, but Butler and Iommi rejected him. They subsequently recruited Vinny Appice, who had served as Black Sabbath's drummer during most of Dio's previous tenure with the band, from 1980–1982. Initial demo sessions with Powell yielded numerous recordings, including two unreleased songs – "The Night Life" (also called "Next Time"), the riff being later used for "Psychophobia" on Cross Purposes, and "Bad Blood", which sounds very similar to "I" on Dehumanizer. These songs can be found, along with other demos and untitled songs, on the Complete Dehumanizer Sessions bootleg. "Computer God" was the title of an unreleased song by The Geezer Butler Band, in 1986 – only the title made it to Dehumanizer. The Geezer Butler Band's version is available as a download on Butler's website. "Master of Insanity" was also an unreleased Geezer Butler Band track and the Dehumanizer version is essentially a re-recording of this. The US-release added a bonus track "Time Machine (Wayne's World version)". This is the first recording of the song, specifically for the soundtrack to "Wayne's World" and ahead of the album sessions. It was also released as a 1-track promo CD. Re-released in 2008 on Rhino Records. Released as Spec/Digi 2 CD with bonus cd in 2011 on EMI.
