Quiet Riot

QR (also known as Quiet Riot or Quiet Riot IV ) is the sixth studio album released in 1988 by the American heavy metal band Quiet Riot. The album featured a major line-up change. Singer and founding member Kevin Dubrow had been fired before the recording sessions began, and replaced by Rough Cutt vocalist Paul Shortino. The band had fired DuBrow mainly because of comments he was making to the metal press about Quiet Riot's supposed superiority over other bands, which strained friendships that members of Quiet Riot had with those bands. Shortino's hiring wasn't the only line-up change, as Chuck Wright had quit the band and was replaced by Sean McNabb. This left the album with the distinction of being the only Quiet Riot release without DuBrow on vocals, or any other original members.
