Fargo Rock City was my first intro to Klosterman. It was pretty well written and funny. For the most part, the rest of his work is the same.
This particular book is broken up into 3 sections. The first section is a series of his interviews with famous folks that he wrote for Spin, Esquire, etc. He interviewed Britney, Bono, Jeff Tweedy from Wilco, Thom Yorke from Radiohead, etc. All of the interviews were entertaining. Mostly because, as in the Billy Joel interview, even if he really likes the person he's interviewing, he'll still be honest in the article.
The 2nd part of the book articles that are just his opinions about certain subjects. As in, which bands are rated right (not overrated or underrated), his very odd stance on stem-cell research (there needs to be more Super People), the upcoming war against robots, and so on. All pretty funny stuff.
The last part is fiction and frankly, I just skimmed it. His non-fiction work was more entertaining.
