Ozzmosis is the seventh studio album by English heavy metal singer Ozzy Osbourne. Recorded in Paris and New York with producer Michael Beinhorn, it was released on 23 October 1995 by Epic Records. The album reached number 22 on the UK Albums Chart and number four on the US Billboard 200. "Perry Mason", "See You on the Other Side" and "I Just Want You" were released as singles. After the release of his sixth album No More Tears in 1991, Osbourne announced that he would retire from music. However, he returned with Ozzmosis in 1995, which featured long-time guitarist Zakk Wylde as well as former Black Sabbath bassist Geezer Butler and drummer Deen Castronovo. Keyboardist Rick Wakeman was invited to play Mellotron on two songs, Perry Mason and I Just Want You. Four years later in 1999, Ozzy would accept Wakeman's invitation to sing on one song on the keyboardist's album Return to the Centre of the Earth. And as for the keyboards throughout the album Ozzmosis, they were played by Producer Michael Beinhorn. The release received mixed reviews from critics. Ozzmosis was one of many Osbourne albums remastered and reissued in 2002. The reissue featured bonus tracks "Whole World's Fallin' Down" and "Aimee", originally released as B-sides to "Perry Mason" and "See You on the Other Side", respectively. The album has been certified double platinum by the Recording Industry Association of America and has sold over 3 million copies. Recording and production Recording took place at Guillaume Tell Studios in Paris, France, Right Track Recording and Electric Lady Studios in New York City, and Bearsville Studios in Woodstock, New York. Production was led by Michael Beinhorn, with Paul Northfield engineering and David Bianco mixing. Writing credits on the album – alongside Osbourne, guitarist Zakk Wylde and bassist Geezer Butler – were shared by John Purdell, Jim Vallance, Mark Hudson, Steve Dudas, Lemmy Kilmister, Duane Baron and Steve Vai. Ozzmosis was Ozzy's first and only album to feature Butler, drummer Deen Castronovo and keyboardist Rick Wakeman. Guitars were by his long-time band member Wylde, although Steve Vai was originally slated to perform on the album after writing songs with Osbourne in 1994 (of which only "My Little Man" remained). Vai reportedly left the project due to a "falling out" with Osbourne, although Wylde maintains they are still friends. Prior to Beinhorn's involvement, Ozzmosis was to be produced by Michael Wagener,
