An iconic L.A. band that laid the groundwork for the metal explosion of the ’80s, Quiet Riot has been rocking for nearly 50 years. ∙ Quiet Riot was cofounded in 1973 by legendary guitarist Randy Rhoads, who left the group in 1979 to play with former Black Sabbath frontman Ozzy Osbourne—and revitalized the singer’s career. ∙ Metal Health, the group’s 1983 debut LP in the US, was the first metal album to reach No. 1 on the Billboard 200 chart and eventually went six-times Platinum. ∙ “Cum On Feel the Noize,” a cover of Slade’s 1973 UK hit, was the first metal song to crack the Top 10 of the Billboard Hot 100 chart and became Quiet Riot’s signature anthem. ∙ “Metal Health (Bang Your Head),” which helped introduce headbanging into pop culture, was the group’s second Top 40 hit and was later included in VH1’s list of the 100 Greatest Hard Rock Songs. ∙ They scored another Platinum album with 1984’s Condition Critical, which featured the minor hit Mama Weer All Crazee Now"—another Slade cover. ∙ Following a breakup and years of shuffling lineups, the original Metal Health band reunited in 1997 when Quiet Riot was invited to play an aftershow party for Marilyn Manson.
