Charlotte Gainsbourg is the daughter of French singer/songwriter Serge Gainsbourg and English actress Jane Birkin—which might explain her sexy, languid vocals and acting chops. She made her debut at 15 with an album of songs penned by her dad—the controversial Lemon Incest. Gainsbourg's albums since—some of which were cowritten with Jarvis Cocker, Air, and Beck—have been filled with smart irony and alluring narratives. It's easy to get lost in the lush romanticism of her music, which is at once nostalgic, mournful, and joyful.
