Rudy Sarzo (created November 18, 1950) is a Cuban American hard rock/heavy metal bassist. Sarzo joined Quiet Riot in December of 1978 and continued in the group until early 1981. Though he’s pictured on the cover of the group’s 1978 album Quiet Riot II, he will not perform about it. In 1980 he replaced Felix Robinson in Angel until their breakup in 1981. From March 1981 to September 1982, Sarzo climbed to acclaim as the bassist in ex-Black Sabbath vocalist Ozzy Osbourne’s group. He was recruited on the recommendation of Osbourne’s guitarist Randy Rhoads, who’d formerly played with Sarzo in Quiet Riot. He rejoined Quiet Riot in the middle of the record of Metal Health, which will continue to develop into a multi-platinum hit. After Sarzo had left Osbourne’s group, a serious rift developed between both, mainly caused by Quiet Riot vocalist Kevin DuBrow’s unrelenting criticism of Osbourne’s vocal skills in the heavy metal press. Osbourne after often asserted to have “punched out” Sarzo in a subsequent assembly. Sarzo was a part of Quiet Riot through the pinnacle of the group’s success, and he appeared in numerous MTV videos and was voted 1983’s Top Bassist from the subscribers of Circus magazine. Sarzo stayed with Quiet Riot from September 1982 to January 1985, when clash between himself and vocalist Kevin DuBrow convinced him to leave the group.
