Quiet Riot is an american heavy metal band, whose 1983 chart topping success helped pave the way for the glam metal scene's next decade of commercial prominence. They are best known for their Metal Health album, which displaced Michael Jackson’s Thriller album from the #1 chart spot. They were founded in 1975 by guitarist Randy Rhoads ( later with Ozzy Osbourne) with the original lineup featuring Kevin DuBrow (whose Steve Marriott influenced vocals powered most of their hits), as well as Kelly Garni (bass) and Drew Forsyth (drums).
