Immensité

"Immensité" was written by Nina Bouraoui and French composer Jacques Veneruso, who also produced the recording. Veneruso had collaborated with Dion on several earlier songs, including "Sous le vent", "Tout l'or des hommes", and "Je ne vous oublie pas". Bouraoui contributed another composition to D'elles, titled "Les paradis". The single was released digitally on 14 May 2007. Because it was not issued on CD, "Immensité" was ineligible for the main singles charts in France, Belgium, and Switzerland, which at the time were based on physical sales.

The music video was filmed at Lake Mead on 5 and 6 April 2007 and premiered on 22 May 2007.

Dion performed "Immensité" during two television specials created for the release of D'elles. She also sang it at a private benefit concert for Sainte-Justine on 4 August 2007. During her visit to France in November 2007, she promoted the song again and included it on the "Taking Chances" French CD single issued at that time. In April 2008, "Immensité" was added as a bonus track to the digital deluxe edition of Taking Chances. Dion later performed it on Star Academy, during her European concerts in 2013, her 2016 tour, and her French concerts in 2017.^[1]
