i might be short-sighted in a kind of nerdish way (since Axel noted this might as well be a book for "nerds") but my impression is that you really cannot be neutral to Sonic Youth.
if that's really the case, and you love them, you will want to have this book. more than a book, it's a work of art. a collection of pictures, memorabilia, essays, diary entries and so on, written by and about Sonic Youth. two colored 7" vynils, with individual contribution from the four band members, round up a package that is nothing short of amazing for any fan.
If you are into Sonic Youth in a nerd way, if you think they are one of the best band ever, if you were in Dusseldorf in 2009 for their exhibitions, you must posses that book.
Curiosities, stories, informations, photos and even more about different moments of their lives. Sonic great!
