Hat off to Ghost who hipped me to this. It's an in-depth survey on glam rock and its followers, by Simon Reynolds, one of the most interesting writers on popular culture from the last times. I know his Retromania, Pops obsession with its own past. Turns out he's my age. So he's lived through both glam and post punk. Just as me: the first as a kid, the second in my twens. Glam and Post punk are the two faces of the same coin. And Reynolds has books on both, which I both have.
