Charlotte Gainsbourg announces the release of her fourth studio album, 'Rest,' out on Because Music / Warner.

All tracks on the album are produced by SebastiAn (Frank Ocean, Kavinsky), except "Rest," composed and co-written by Guy-Manuel de Homem-Christo, and "Songbird in a Cage," composed and written by Paul McCartney. 'Rest' also features collaborations with Owen Pallett, Connan Mockasin, and others.

'IRM,' Gainsbourg's 2010 album, saw Beck translating Gainsbourg's ideas into song, and Gainsbourg interpreting them with the gossamer tenderness of her sung delivery and trademark whisper.

'Rest' is the first album by Gainsbourg whose lyrics she wrote, having previously felt daunted by the desire to poetize her ideas. Even more intimidating was the idea of putting her thoughts to verse in French. "In the shadow of my father [pioneering French musical superstar Serge Gainsbourg], writing in French was something I never dared to do," she says. Grappling with the recent death of her sister, fashion photographer Kate Barry, however, created an immediacy—and from within the "intense grief" it was "easier to express certain things" in French.

On the album, Gainsbourg addresses personal topics ranging from familial loss, to the tensions between her shyness and her life as a performer and public figure, to charmingly illogical childhood fears—with lyrics pried from her own diaries, rendered here in French and English.

Despite her lyrical confrontations of grief, Gainsbourg has created an album that never becomes stuck in a given emotional state or set of musical references. While tracks like "Ring A Ring O' Roses" evoke Charlotte Gainsbourg's past work with Air (on her sophomore album, 5:55), Rest is also rife with funk flourishes, as on "Sylvia Says," psychedelic vocal distortions, as on McCartney collaboration "Songbird in a Cage," carnivalesque MIDI, as on "I'm A Lie," and playful disco beats, as on the energized album closer "Oxalis." This last, propulsive and even exuberant song also happens to be about death, displaying the dynamism with which Gainsbourg approaches the subject. "Oxalis" takes a self-reflexive approach, with the artist singing about finalizing her own portrait of grief. As Gainsbourg explains, "Through the toughness of the words chosen there lays—for me—an all-consuming love."

Now, the upcoming 'Rest' marks Gainsbourg's achievement of the lyrical confidence to get unprecedentedly candid, and to trust her own words' ability to communicate universal pains of loss through personal ones. Says Gainsbourg, "It's the first time that I've surrendered myself, and the end result belongs to me."
