This is a wildly uneven book, observant in places and lazy in others (one picture says that Southside Johnny is playing guitar behind Bruce when it's obviously Nils), but I'm glad it exists, if only to serve as a corrective to Dave Marsh's stenographic biographies.
At the time this book was published, Mike Appel had been all but airbrushed out of the Bruce Springsteen narrative, considered an incidental figure at best, when in truth he is likely the most important person in the whole enterprise. As Eliot makes clear, before Born to Run came out, Bruce had scant support from his label or AM radio, and Appel singlehandedly bought him enough time to create the album that changed everything. Very simply: no Appel, no Springsteen as we know him.
Anyone who's heard Bruce give an interview up to about 1980 understands that he saved all his insight for the music, and that comes to a head in the depositions, where Bruce alternates between not knowing what the lawsuit is even really about and berating opposing counsel because he didn't realize his testimony would be used against him in court.
In the end, this isn't the hammer blow to Springsteen's reputation that the book jacket suggests, but it is a sad excavation, one of a million such sad stories in the music business, of a relationship probably destined to fail.
