Encore un soir features songs produced by Jean-Jacques Goldman, Jacques Veneruso, Zaho, Silvio Lisbonne, Humberto Gatica and Scott Price.

In August 2015, Dion's manager, Aldo Giampaolo, announced that the singer will be releasing French and English language albums in 2016 and 2017, respectively.

[2] During a series of interviews with various news outlets that took place on 12 May 2016 at The Colosseum at Caesars Palace, Dion announced that the upcoming French album would be released in August 2016.

[1] On 9 November 2015, celinedion.com began a contest which allowed for fans to submit a track to be selected for Dion to record for this album.

On 2 December 2015, after more than 1000 votes, Dion's website announced that the winner of the contest was Daniel Picard, and his track titled, "À la plus haute branche" will be included on the album.

[4][5] Dion and Angélil's vision of a new collaboration with legendary French artist Jean-Jacques Goldman came to fruition with "Encore un soir", marking a long-awaited reunion, after over twelve years.

For the first time, the French artists Francis Cabrel and Serge Lama co-wrote a song for Dion ("Plus qu'ailleurs").

[4] Jacques Veneruso, one of her most trusted collaborators in recent years, has written and composed a new song as well ("Si c'était à refaire").

[4] Grand Corps Malade has once again, after Sans attendre, offered his poetry to this new album on "L'étoile" and "Les yeux au ciel".

One of them was Zaho and LNT Musik (Ludovic Carquet and Therry Marie-Louise) who wrote and produced "Ma faille", "Tu sauras" and "À vous" (on the Deluxe edition).

[4] Other new partners include Florent Mothe and Mutine (Manon Romiti and Silvio Lisbonne) who wrote "L'étoile", "Les yeux au ciel" and "Le bonheur en face".

[4] Dion wanted to pay tribute to Quebec rich musical repertoire by reinterpreting the classic Robert Charlebois song "Ordinaire".

[4] Daniel Picard saw his song "À la plus haute branche" chosen from over 4,000 submissions following a contest launched on Dion's website.

Aside from "À vous", the Deluxe edition also includes "Ma force" written by Vianney and a remastered version of "Trois heures vingt", Dion's 1984 song.

[6] It was featured on Encore un soir because Angélil was particularly fond of this song, which was played during his funeral service at exactly 3:20 pm, marking the commencement of the ceremony.

[6] Other songs from the album performed on this tour included "Encore un soir", "Ordinaire" and "À la plus haute branche" (in Canada).

It garnered positive reviews from music critics and topped the charts in France, Quebec and the French-speaking part of Switzerland.

[24][25] On 7 September 2016, Dion performed "Encore un soir" and "Les yeux au ciel" for the very first time on television on M6's Music Show – 100% tubes 2016 in France.

[26] On 1 October 2016, she also performed "Encore un soir" and "Les yeux au ciel" on Le Grand Show on France 2.

"[31] Nicolas Houle from La Presse wrote that "Encore un soir", written by Jean-Jacques Goldman, comes with remarkable restraint and subtlety and is probably the strongest track on the album.

[32] He also praised "Ordinaire", originally sung by Robert Charlebois, and also two songs written by Grand Corps Malade ("L'étoile" and "Les yeux au ciel") and "À la plus haute branche" by Daniel Picard.

[32] Alain de Repentigny, from La Presse+ wrote that the album is orchestrated and praised "Plus qu'ailleurs" (written by Francis Cabrel and Serge Lama), "L'étoile" (an uptempo track with music by Florent Mothe and Mutine), "Encore un soir", "Je nous veux" and "Toutes ces choses" (both written by Marc Dupré), "Si c'était à refaire" (by Jacques Veneruso), "Tu sauras" (by Zaho) and "À la plus haute branche".
