While touring America with Thin Lizzy in support of the band's album Black Rose: A Rock Legend, Moore suddenly quit the band and moved to Los Angeles, hoping to establish a solo rock presence. With the opportunity to tour America in support of Van Halen, Moore recruited his one-time Thin Lizzy bandmate, drummer Mark Nauseef (Elf, the Ian Gillan Band), and vocalist/bassist Glenn Hughes (Trapeze, Deep Purple), dubbing the band "G-Force". Several months into rehearsals, Hughes left the band after an alcohol-fuelled altercation with Moore and was replaced with vocalist Willie Dee (born William Daffern; formerly of Captain Beyond and Pipedream) and Motown session bassist Tony Newton. The subsequent tour was a success, and the band went on to support Whitesnake on their 1980 Ready an' Willing tour. However, the project was short-lived, only producing the one eponymous album, which was re-mixed by Dennis Mackay. The album consisted of more conventional hard rock radio-oriented music than Moore's previous efforts. The band also recorded the Newton and Dee-penned song "Trust Your Lovin'", only released as a B-side to the 7" single "You".
