I spent the last half of the Seventies in grad school, so missed some minor developments like punk and new wave. By the time I got around to them, they sounded pretty much like extensions of the rock I’d already been listening to. That’s what happens when you take things out of context. Greil Marcus’s Ranters and Crowd Pleasers went a long way to filling me in on what I’d missed. The voices that carried me through the decade belonged to Stevie Wonder, Dylan, and the new kid on the block, Bruce Springsteen. Dave Marsh’s Born to Run tells you why.
