A wide-ranging look at contemporary pop's retro fixation - its obsession with its own past. The focus is on pop music but Reynolds takes in a range of other strands of popular culture, often in impressive depth. I skimmed large parts of it - as much as I love listening to music, I don't at all have the obsessive interest in analysing it and tracing its history or cultural significance that Reynolds himself clearly does - but it was worth the read.
