Ozzy Osbourne is an English heavy metal vocalist from Marston Green, Warwickshire. After he was fired from Black Sabbath early in 1979, Osbourne formed a solo band (initially known as Blizzard of Ozz) in November of that year with guitarist Randy Rhoads, bassist Bob Daisley and drummer Lee Kerslake. Since its inception, the group's personnel have changed frequently. The current lineup includes guitarist Zakk Wylde (who first joined in 1987 until 1992, spent a second tenure in the band from 2001 and 2009, and most recently rejoined in 2017), bassist Rob "Blasko" Nicholson (a member since 2003), keyboardist and rhythm guitarist Adam Wakeman (who first joined as a touring musician in 2004, and was made an official member with the release of Scream in 2010), and drummer Tommy Clufetos (since 2010).
