A French couple who love Gainsbourg almost as much as they love each other and capture their moments of transitory passion in brooding black and white photography, John And Jehn may sound like a walking cliché. But their debut album has some exquisite pop noir moments, evoking The Breeders’ combination of sweetness and hauteur and The Velvets’ cool, dark, tambourine-speckled grooves. And all, you imagine, in the course of one post-coital Gauloise.
