QR (album)

QR (also known as Quiet Riot, Quiet Riot IV, or QR IV) is the sixth studio album by American heavy metal band Quiet Riot, released on October 21, 1988. Singer and founding member Kevin DuBrow had been fired before the recording sessions began, and replaced by Rough Cutt vocalist Paul Shortino. The band fired DuBrow because of his reputation for talking down to other bands in the press. This strained relationships the other memebers had with those bands. This left the album with the distinction of being the only Quiet Riot release without DuBrow on vocals during his lifetime, and the first without any original members. Bassist Chuck Wright also quit the band and was replaced by Sean McNabb.

The album also featured studio musicians Jimmy Waldo (keyboards) and Jimmy Johnson, who played bass on "Stay with Me Tonight" and "Coppin' a Feel". The album was produced by Spencer Proffer, who had produced every Quiet Riot U.S. released album up to this point. Paul Shortino and Sean McNabb later played together on Rough Cutt's Sneak Peek EP.
