The album was largely co-written and produced by Ronson and Jeff Bhasker over 18 months in studios across London, Memphis, Los Angeles and New York City. The bulk of the lyrics were written by American novelist Michael Chabon, and the LP also features significant vocal and instrumental contributions from Tame Impala's Kevin Parker. Other contributors include Miike Snow's Andrew Wyatt, producer Emile Haynie, Simian Mobile Disco's James Ford, TNGHT's Hudson Mohawke and DJ Zinc.
