Tells the fantastic story of the "last avant-garde in architecture", the deeply influential Japanese metabolism group through a series of interviews putting the movement into context. The interviews are done mostly by Koolhaas and Obrist. Supplemented with pictures of the relevant projects, it tells the grand story of metabolism in and excellent and interesting way.
Sometimes, you wish for more facts about specific projects. There are also some shortcomings in graphical design i.e. hard to read texts due to color and placement close to the spine. This and cheap paper stops it from being a five.
However, it is an absolute must for anyone interested in Japanese architecture.
