Of the 60-something books we've published in the series so far, none polarizes opinion more than Stephen Catanzarite's volume on U2. There's a great new review of it on Inside Catholic.com, written by Mark Judge, opening with the line "Stephen Catanzarite has written arguably the most important book about rock music of the young 21st century". People either really love this book, or it drives them up the wall, which was clearly going to be the case even as I read Stephen's compelling proposal, a few years back.
I can only think of two volumes in the entire series, for which I've never seen or heard a single negative word - Mark Polizzotti's Dylan book, and Dan LeRoy's book on the Beastie Boys. Of course, feel free to disabuse me of that notion, in the comments section below. Such is the beauty of the internet!
