Christophe is a glider. Fifty years of this. So when it comes to revisiting his repertoire with guests - the classic "duet album" - Christophe suspends his flight. Until he spends nearly 2 years on "Christophe Etc." Divided into two feature films, two volumes, "Christophe Etc" therefore welcomes guests whose only common point remains French song. From Etienne Daho on "Le petit gars," to the Americans SonLux on "Les mots bleus," from Eddy Mitchell on "Parfum d'histoires," to Nusky & Vaati on "Succès fou," so many vignettes that tell the life of an artist who has been busy since 1965, never doing the same thing twice. "To all the guests I said: 'sing everywhere, fill the tracks,'" he explains. Once the songs were recorded, Christophe, like a couturier-producer, worked on the hems, adjusted the folds, placed his voice in the interstices until these pieces fell just right. This is what we call "ready to sing," never out of style, always ahead even when it comes to revisiting the past. A trademark that makes this "Etc" a little more than a stylistic exercise. "I revisited everything. For me, this is not a duet album: it's an original album."
