Joanne Robertson released her debut album, 2008โs The Lighter, 16 years ago; since then, her voice has frayed at one end and calcified at the other, and itโs never sounded as beautiful and electrifying as it does on Backstage Raver. Shades of every great yearner are collected in her raw, emphatic pipes: Hope Sandoval, Sky Ferreira, Neko Case, Cat Power, so many more; maybe you canโt always make out the words, but you always know what she means.
