 It is the band's first album in five years, and marks the return of singer Kevin DuBrow after his firing in 1987.
 It is bassist Kenny Hillery's only studio album with the band, and drummer Bobby Rondinelli plays on several songs.
 Many of the album's songs were featured in Charles Band's movie "Dollman vs. Demonic Toys", with the album itself being released on Moonstone Records, the soundtrack offshoot of Band's film company Full Moon Entertainment.
Paul Shortino
Paul Shortino (born May 14, 1953) is an American rock singer and musician who has sung for several bands, including Rough Cutt/The Cutt, Quiet Riot, Bad Boyz, and Shortino.
 He briefly recorded with J.K. Northrup as the duo Shortino/Northrup.
 He has also recorded as a solo artist, writing and performing the song "E.G.G.M.A.N." as the theme for Dr. Eggman in Sonic Adventure 2 for Sega (this song was later revised by Remix Factory in Shadow the Hedgehog as "E.G.G.M.A.N. Doc Robeatnix Mix").
 In 1985, Shortino recorded lead vocals for the Heavy Metal benefit project Hear 'n Aid.
 The single from this project, "We're Stars" also features lead vocals by heavy metal singers Ronnie James Dio, Rob Halford, Geoff Tate, Don Dokken, Kevin DuBrow, Eric Bloom and Dave Meniketti.
Rehab (Quiet Riot album)
Rehab is the eleventh studio album released from the heavy metal band Quiet Riot in 2006.
 It is their first studio release since 2001's "Guilty Pleasures".
 This is the last Quiet Riot studio album to feature lead singer Kevin DuBrow before his death in November 2007, which caused the band to split, though they would eventually reform in 2010 and continue to record and tour.
QR (album)
QR (also known as Quiet Riot, Quiet Riot IV, or QR 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 was not 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 (until 1993's "Terrified").
QR III
QR III is the fifth studio album released by American heavy metal band Quiet Riot.
 It was released in 1986 on Pasha/CBS.
 It is the last album to feature lead singer Kevin DuBrow until the 1993 album "Terrified".
Alive and Well (Quiet Riot album)
Alive and Well is the ninth studio album by heavy metal band Quiet Riot.
 It was recorded following a reunion of the classic 80's Quiet Riot lineup of Kevin DuBrow, Rudy Sarzo, Carlos Cavazo, and Frankie Banali.
 It featured eight new songs alongside updated versions of six of their classics, including "Cum On Feel The Noize", "Metal Health" and "Mama Weer All Crazee Now", as well as a cover of "Highway to Hell" by AC/DC.
 This track had previously been released on the AC/DC tribute album "Thunderstruck".
Quiet Riot 10
Quiet Riot 10 (also alternatively known as just 10, or Quiet Riot Number 10) is the twelfth studio album by the heavy metal band Quiet Riot, which was released on June 27, 2014.
 It is their first studio album since 1988's "QR" not to feature longtime and founding vocalist Kevin DuBrow in any newly recorded material, due to his death in November 2007.
 It is also the band's first album since reuniting in 2010.
 Although a studio album, the final four tracks on "Quiet Riot 10" are live performances taken from some of the band's final shows with DuBrow in 2007.
 Love/Hate vocalist Jizzy Pearl joined the band in November 2013 and performs lead vocals on the six studio tracks.
