On 18 August 2015, a new temporary site was launched, presenting a countdown whose timer was set to end on 28 August 2015, announcing Farmer's return with a brand new record. Its background pictured Farmer and British singer Sting, indicating a collaboration. On 28 August 2015, their single "Stolen Car" was available on iTunes. It is a new version of a song which was originally released on Sting's 2003 Sacred Love album, Farmer's and Sting's duet hit number one on the French chart. A promo single "Insondables", was released on 28 October 2015. "City of Love" was released as the second single of the album on 8 January 2016, followed by a remix by Martin Kierszenbaum featuring Shaggy in February 2016, also peaking at number one on the French chart.
Release and promotion
On 16 September 2015, French magazine Gala announced Farmer's upcoming studio album title. It was then officially confirmed on 16 September 2015 by the singer's recording label, Polydor, through its Facebook page. Another temporaneous site was then launched with a timer set to the album release, as previously done with the "Stolen Car" single. Its layout pictured a nebula with flowing stars in the background and a deep, loud noise added, just like the one that could have already been heard with "Stolen Car"'s site, possibly matching the album core theme.
