High Quality Content by WIKIPEDIA articles! Rudy Sarzo is a bass guitarist, born Rodolfo Maximiliano Sarzo Lavieille Grande Ruiz Payret y Chaumont, in Havana, Cuba on November 18, 1950. He emigrated to the United States in 1961. Sarzo has played with many well known heavy metal acts including Quiet Riot, Ozzy Osbourne, Whitesnake, Manic Eden, Dio and Blue Öyster 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.
