As of February 2011, Paolo Nutini was in the studio working on new material. He toured for two years after the release of his second studio album, followed by a hiatus from music in which he went home and "spent a good few months partying there, then I detoxed, then I retoxed." During this time Nutini was "writing along and recording little bits," for the following two years Nutini put the "spotlight" on the album stating he had "never written as much, but I had to take a bit of time. My writing used to come from a different place. I used to be more picky and there used to be a more pop sensibility to what I would naturally come up with." This was followed by Nutini writing "nothing but poetry", which he use to hate the notion of "trying to turn it into a verse-chorus-verse-chorus-type song, and struggled with it and got no pleasure from it whatsoever." The album's recording took place in a variety of locations, including Grouse Lodge Studios in Ireland; RAK Studios, Sarm Studios, Studio 45, The Premises, The Strong Room in London; Studio Barxeta in Valencia, Spain; Sunset Sound in Los Angeles; The Old Police Station as well as Cava Sound in Glasgow and Toy Room Studios in Brighton.
