Ozzy Osbourne has teamed up with Celine Dion and Britney Spears' former producer on his first album for six years. The rocker plans to release BLACK RAIN on 22 May (07). The Prince of Darkness co-produced the album with KEVIN CHURKO. Osbourne insists the album is one of his darkest - because all the songs on it have been inspired by tragedy. He explains, "I just thought there's so much f**king bad news, the only way I can release it is to put it in a song."
