Probably the best book on Pink Floyd. Blake takes a fairly typical approach in this band history/biography. But it's well researched, well written, and comprehensive in following the band from its beginnings through 2007.
This book's focus is as narrow as the title suggests. And Scarfe is a cartoonist, not a writer. But if you are interested in the album and the film that followed, you will enjoy this book produced by one of the film's directors.
