I bought this book before its predecessor, but that didn't matter at all. It's basically a quality collection of street art pics, with some accompanying quirky blurb in places (some of which is entertainingly worth reading, some less so).
As street art books go, it's up there with the good'uns, but my main criticism is that I would have liked whatever artist/location info was available to appear alongside the photos on the pages, rather than just a small Picture Credit/Attributed Artists paragraph at the end of the book. Of course info is limited when you are talking about photos of street art contributed by numerous people, but still I'd have liked whatever sketchy info was available to be there with the photos.
Overall, it's a nice varied collection.
