QR is an album released in 1988 by the band Quiet Riot. This is the only Quiet Riot album which features Paul Shortino (Rough Cutt, The Cutt, Badd Boyz, Shortino) on lead vocals. It is also the only Quiet Riot album which does not feature the late Kevin DuBrow on lead vocals or any other then-surviving original members. It is also the only Quiet Riot album to feature Sean McNabb on bass. To some fans, it may be labeled "QR IV."Reaction to the album at the time was tepid, but did manage to attract a bit more interest than the previous album (and any that would follow).
Paul Shortino and Sean McNabb later played together on Rough Cutt's Sneak Peek EP.
