Following the touring cycle for Cross Purposes, bassist Geezer Butler quit the band for the second time. "I finally got totally disillusioned with the last Sabbath album, and I much preferred the stuff I was writing to the stuff Sabbath were doing". Butler formed a solo project called GZR, and released Plastic Planet in 1995. The album contained the song "Giving Up the Ghost", which was critical of Tony Iommi for carrying on with the Black Sabbath name, with the lyrics: You plagiarised and parodied / the magic of our meaning / a legend in your own mind / left all your friends behind / you can't admit that you're wrong / the spirit is dead and gone ("I heard it's something about me..." said Iommi. "I had the album given to me a while back. I played it once, then somebody else had it, so I haven't really paid any attention to the lyrics... It's nice to see him doing his own thing – getting things off his chest. I don't want to get into a rift with Geezer. He's still a friend."Following Butler's departure, newly returned drummer Ward once again left the band. Iommi reinstated former members Neil Murray on bass and Cozy Powell on drums, effectively reuniting the 1990 Tyr line-up. The band enlisted Body Count guitarist Ernie C to produce the new album, which was recorded in London in autumn of 1994. The album featured a guest vocal on "Illusion of Power" by Body Count vocalist Ice-T. The resulting Forbidden was released on 8 June 1995, but failed to chart in the U.S. The album was widely panned by critics; AllMusic's Bradley Torreano said "with boring songs, awful production, and uninspired performances, this is easily avoidable for all but the most enthusiastic fan"; while Blender magazine called Forbidden "an embarrassment... the band's worst album".Black Sabbath embarked on a world tour in July 1995 with openers Motörhead and Tiamat, but two months into the tour, drummer Cozy Powell left the band, citing health issues, and was replaced by former drummer Bobby Rondinelli. "The members I had in the last lineup – Bobby Rondinelli, Neil Murray – they're great, great characters..." Iommi told Sabbath fanzine Southern Cross. "That, for me, was an ideal lineup. I wasn't sure vocally what we should do, but Neil Murray and Bobby Rondinelli I really got on well with."After completing Asian dates in December 1995, Tony Iommi put the band on hiatus, and began work on a solo album with former Black Sabbath vocalist Glenn Hughes, and former Judas Priest drummer Dave Holland. The album was not officially released following its completion, although a widely traded bootleg called Eighth Star surfaced soon after. The album was officially released in 2004 as The 1996 DEP Sessions, with Holland's drums re-recorded by session drummer Jimmy Copley.In 1997, Tony Iommi disbanded the current line-up to officially reunite with Ozzy Osbourne and the original Black Sabbath line-up. Vocalist Tony Martin claimed that an original line-up reunion had been in the works since the band's brief reunion at Ozzy Osbourne's 1992 Costa Mesa show, and that the band released subsequent albums to fulfill their record contract with I.R.S. Records. Martin later recalled Forbidden (1995) as a "filler album that got the band out of the label deal, rid of the singer, and into the reunion. However I wasn't privy to that information at the time". I.R.S. Records released a compilation album in 1996 to fulfill the band's contract, titled The Sabbath Stones, which featured songs from Born Again (1983) to Forbidden (1995).
