RavePitchforkThe book speaks to pop music’s effect on future generations of norm-breaking artists, but also on public perceptions of gender and its engagement with race and class politics ... Part of the joy of reading Glitter Up the Dark lies in Geffen’s sheer depth of research ... Identity has never been a fixed idea—instead, it’s always been a conduit for grand expressions of selfhood. Geffen seamlessly imparts this idea into a patchwork of music history ... offers a musical roadmap for such an activation, one paved with countless examples of gender as a device for personal metamorphosis. It’s an essential contribution to the modern music-book canon, made all the more intimate in Sasha Geffen’s hands.
