After their previous two albums, "Nightlife" and "Fighting", failed to generate sales, Thin Lizzy were given one last chance by their label, Vertigo Records. The band wrote songs and collected ideas in a studio in Buckinghamshire in late 1975, then convened at Ramport Studios in London in the new year. They selected John Alcock as their producer, for he had worked in the studio extensively. The band worked diligently through February on the album. However, guitarists Scott Gorham and Brian Robertson felt that the speed at which it was completed adversely affected its quality. Both stated that the tightness of the songs made the album feel rigid. In particular, Robertson said he would have liked more freedom to improvise his lead guitar parts. Gorham also criticized Alcock's production, saying that he didn't particularly care for his guitar tone on the album.
