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.
