Best known for her irresistible singles as an iconic French yé-yé girl, Vartan delivered plenty of curveballs over her half-century-plus career. These include "L'homme en noir," a slide-guitar-inflected version of Roy Orbison's "Pretty Woman"; her ennui-soaked, chanson-tender "La vie d'artiste"; and Vartan's smoking, Vegas-ready "Rock Medley."
