As usual, I found myself impressed by music criticism in general -- the best of it is often better than most contemporary poetry criticism that I read. The critics seem to care about the actual music more than "placing" in artist in some sort of critical continuum or to flog some theory or another. Music criticism can be banal too, of course, but not as consistantly so as lit crit.
As for this book, it was a tad spotty, thus my middling rating. The good stuff was quite good, the rest mediocre. Barry Mazor's "The Legacy of Little Miss Cornshucks" was perhaps my favorite piece -- a legacy-restoration exercize that was informative and really well put together. But Dan Baum's medical-musical investigation into "Jake Leg" was un-put-downable. Gene Santoro's profile of Willie Nelson at 70 interested me far more than the subject it addressed...and then I came around to the fact I have probably underestimated Willie. Must remedy this some day. Michaelangelo Mantos' list of 69 love songs by year underscores my ignorance and made me want to be a better listener.
This is the old fogey stuff, of course, but I'm an old fogey. The youngsters impressed me with their verve, but I was baffled much of the time too. But that's not necessarily their fault. Robbie Fulks' account of playing at the Grand Ol' Opry was wonderful. But "Emo: Where the Girls Aren't" and some of the hip-hop things were too in-the-know for me to figure out what was going on. But I'm hardly the ideal audience for such stuff.
