Charlotte Gainsbourg was nervous. She had never toured before, and no one knew what to expect as she took to the stage last weekend, at what must have been the most crowded concert to date at the Hiro Ballroom. But as the show went on, Gainsbourg’s confidence grew, aided by cheers coming from the crowd, in both French and English. On IRM, Gainsbourg’s new album written and produced by Beck, her ethereal voice wafts and wanes over eerie melodies reminiscent of Beck’s own Sea Change. It’s no surprise then that Gainsbourg’s sold-out appearances at Manhattan’s Hiro Ballroom and Brooklyn’s Bell House drew such attention. She’s one of the most interesting artists working today — giving a heart-stopping performance in Lars von Trier’s film Antichrist and creating one of the most beautiful albums released in the last year. And to top it all off, she is simply one of the nicest, most gracious people we have ever interviewed.
