Background: Ratt is an American heavy metal band that had significant commercial success in the 1980s, with their albums having been certified as gold, platinum, and multi-platinum by the RIAA. The group is perhaps best known for hit singles such as "Round and Round" and "Lay It Down", tracks that ranked on Billboard's top 40 at No. 12 and No. 40, respectively, as well as other songs such as "Wanted Man", "You're in Love" and "Dance".
Context: The origins of Ratt go as far back as 1973 in Hollywood, with a band called Firedome, founded by singer Stephen Pearcy with a few friends. In 1974 the band broke up, with Pearcy forming Crystal Pystal. The name Crystal Pystal was later changed to Buster Cherry, which turned into Mickey Ratt in 1976.  Guitarist Robbin Crosby in those same years had been a member of the bands Metropolis with Tommy Asakawa and Parramore McCarty, Xcalibur, Phenomenon, Secret Service and Mac Meda with Askawa.  Mickey Ratt went through various line-up changes. Members included guitarists Jake E. Lee, Chris Hager, Paul DeNisco, and Bob DeLellis, bassists Matt Thorr, Tim Garcia, Mike New and Dave Jellison, and drummers John Turner, and Bob Eisenberg. The various Mickey Ratt line-ups released several demos compilations and a live concert recording.  In 1980, to increase their chances of landing a recording contract with a major label, the band recorded a single called "Dr. Rock" / "Drivin' on E", which was given to fans at their early Los Angeles club shows.  In 1981, the band's name was shortened to Ratt. Crosby played with the band later in the year. Guitarist Warren DeMartini, recommended by Lee, joined the band in January 1982. Bassist Gene Hunter (from Jake E. Lee's Teaser) and drummer Khurt Maier (who played drums on the early "Tell the World" recording featured on the compilation Metal Massacre I) temporarily played in Ratt before the arrival of Bobby Blotzer (ex-Vic Vergeat) and Juan Croucier (previously with Dokken, and musically active since 1973). DeMartini was only 18 years old when he was called up to Los Angeles to join Ratt. At the time he was attending college in San Diego and was reluctant to drop out to join a band that had, so far, had only limited success. Marq Torien briefly replaced DeMartini, though he returned in time for the recording of their first EP, later in 1982.  The self-titled independent EP was well-received and brought the band to the attention of Atlantic Records which signed them. Ratt immediately started writing and recording their first full-length album. Out of the Cellar was released in March 1984 and was praised by both fans and critics. Pearcy's raspy yet bluesy vocals were noted for melding with the pyrotechnic guitar playing of twin leads Crosby and DeMartini, combining the then-prevalent Van Halen and Aerosmith-influenced bravado elements with the then-novel muted, staccato guitar-picking style of Judas Priest. Tawny Kitaen, who was previously in a relationship with Crosby, agreed to appear on the cover of their debut full-length album. She also appeared in their video for "Back for More" and on their EP from the previous year.  The album scored much radio and MTV play with songs like "Round and Round" (which peaked at No. 12 on the Billboard Hot 100 chart), "Wanted Man", "Back for More", and "Lack of Communication". Their music videos exposed them to an excited teen audience first tuning into the then fledgling MTV cable network. Milton Berle's guest appearance, dressed in his Uncle Miltie drag character, in the video for "Round and Round" helped draw even more attention to the band.  Out of the Cellar became a commercial success, going platinum many times over in the United States, as well as making Ratt stars at home and in the Far East. The album release was capped off by a successful world tour that saw the band sell out stadiums and arenas worldwide, sharing the stage with such acts as Billy Squier, Ozzy Osbourne, Blackfoot, Iron Maiden, Motley Crue, Twisted Sister and Lita Ford. Out of the Cellar is today widely regarded as the band's best work and a definitive moment in 80s heavy metal, while "Round and Round" scored at No. 61 on VH1's Greatest Hard Rock Songs Show.  The band's second full-length album Invasion of Your Privacy was released July 1985. It peaked at No. 7 (which is the same position that Out of the Cellar peaked). The album met mostly positive reactions from fans and critics. Allmusic.com has called it "another batch of solid pop-metal tunes". It contained the favorites "You're in Love" and "Lay It Down" (which made No. 40 on the Hot 100) that assured the band a presence on radio and MTV. Footage from the band's performances at Hirsch Memorial Coliseum in Shreveport, Louisiana and the Mississippi Coast Coliseum in Biloxi, Mississippi were featured in the video to "You're In Love".  DeMartini and Crosby's impressive guitar solos and Pearcy's highly sexual lyrics helped to further define the Ratt sound. Although it did not achieve the sales figures or the status of their debut, Invasion of Your Privacy nonetheless was certified double platinum (selling over two million copies) and remains highly regarded amongst fans.  A couple months after the album release, the band released a home video titled Ratt: The Video. The video featured the music videos from the Ratt EP, Out of the Cellar and Invasion of Your Privacy. The video is currently out of print and is very rare and difficult to find. The video was the first commercially available video to certify Gold sales status in the USA and eventually reached Platinum.  The model on Invasion's cover is Playboy Playmate Marianne Gravatte, who also made an appearance in the "Lay It Down" music video. Using a beautiful female model on an album cover later became a trend copied by many glam metal bands of the 1980s, such as Great White, and Slaughter, who coincidentally featured Robbin Crosby's wife on the cover of their debut album. Pearcy himself soon posed for Playgirl (August '86 issue). Invasion of Your Privacy was also one of the many albums that received the attention of the Parents Music Resource Center since the cover and the album title were a reference to voyeurism. The Tipper Gore-led organization presented it at a U.S. Congressional hearing on September 19, 1985 dealing with parental advisory labels on albums that display "inappropriate" content. The band toured extensively in the United States and Japan sharing stage with the likes of Bon Jovi, Ozzy Osbourne and Iron Maiden. In August 1985 the band played on the Monsters of Rock festival in Castle Donington, England, along with ZZ Top, Bon Jovi, Metallica and Magnum.
