Is she a populist or an unwavering radical? A pandering megastar or an avant garde visionary gone mainstream? These are the questions at the heart of Lady Gaga’s career, the subtext of all her music. Whatever your opinion, there’s no denying her influence on the future of pop music as a serious art form. Lady Gaga is honest — brutally honest. She’s inventive, no matter how obvious her source material. And she’s devoted herself to making art that brings the uncomfortable truths of experimental music to a broader base. But still more remarkable is how Gaga’s approach somehow, inexplicably, makes her audience more receptive to the progressive wrinkles she brings to the radio pop arena. Her music doesn’t just stretch boundaries; it makes that boundary-pushing accessible to listeners typically unmoved by the demands of such music. That’s powerful. Really powerful.
