Rudy Sarzo is a Cuban American hard rock/heavy metal bassist. Sarzo has played with many well known heavy metal acts including Quiet Riot, Ozzy Osbourne, Whitesnake, Manic Eden, Dio and Blue Oyster Cult.
From March 1981 to September 1982, Sarzo rose to fame as the bassist in ex-Black Sabbath vocalist Ozzy Osbourne’s band. He was recruited on the recommendation of Osbourne’s guitarist Randy Rhoads, who had previously played with Sarzo in Quiet Riot. Sarzo’s playing can be heard on Osbourne’s Speak of the Devil and Tribute live albums, though he never appeared on a studio album with Osbourne. The liner notes of Osbourne’s 1981 studio album Diary of a Madman list Sarzo as the bassist, though Bob Daisley actually played bass on the recordings.
Following Rhoads’ death in a plane crash in 1982, Sarzo became disillusioned and left Osbourne’s band. He rejoined Quiet Riot in the midst of the recording of Metal Health, which would go on to become a multi-platinum hit. After Sarzo had left Osbourne’s band, a serious rift developed between the two, primarily the result of Quiet Riot vocalist Kevin DuBrow’s persistent criticism of Osbourne’s vocal abilities in the heavy metal press. Osbourne later frequently claimed to have “punched out” Sarzo in a later meeting. Sarzo was a member of Quiet Riot during the peak of the band’s success, and he appeared in numerous MTV videos and was voted 1983’s Top Bassist by the readers of Circus magazine. Sarzo remained with Quiet Riot from September 1982 to January 1985, when friction with vocalist Kevin DuBrow convinced him to leave.
