I don't imagine that you're looking at this book if you're not already a big Radiohead fan, so you're lucky that this book's target market is definitely you. There is a lot of good artwork, sketches, and lyric pages from Stanley Donwood and Dr. Tchock (Thom Yorke) from the OK Computer era through to the recent artwork for Yorke's The Eraser solo album. One of the things that I found most interesting was that the Hail to the Thief word collage/maps were identified as the cities on which they're based. Of course, NYC was easy, but you probably had to be a real geography whiz to know the rest.
Anyhow, for this price, it's a good book to flip through, although your friends might give you some funny looks when they see the title.
