Dehumanizer  by Black Sabbath

Dehumanizer, released on June 22, 1992, is the tenth studio album by Black Sabbath and marked the major return of Ronnie James Dio on vocals after a decade. The album reunited the legendary lineup from the Mob Rules (1981) era: Ronnie James Dio (vocals), Tony Iommi (guitar), Geezer Butler (bass), and Vinny Appice (drums). The album was recorded at Rockfield Studios in Wales.

It is considered one of the band's most "hard" and dark records, with raw production that borders on doom metal. Dio's lyrics moved away from fantasy and focused on the modern world, technology (Computer God), and social criticism (TV Crimes).

Although in 1992 the music scene was dominated by grunge, Dehumanizer managed to bring Black Sabbath back to the Billboard Top 50 (No. 44) for the first time in nine years. Despite initial mixed reviews, it is now recognized as one of the most underrated and solid albums of the post-Ozzy era. This particular reunion ended abruptly in November 1992, when Dio refused to open for Ozzy Osbourne's concerts in Costa Mesa, leading to his departure and his temporary replacement by Rob Halford for those performances.
