If you love Pink Floyd as much as I do, then this one of the many books you should have in your collection. My only reasons for this is that there a number of cool color photos that show up that haven't been published elsewhere. Plus, there is a good interview with Ron Geesin on his maddening experience of co-writing and trying to conduct and record the musical elephant "Atom Heart Mother". There isn't much else to read that you haven't already found out in Nicholas Schaffner's "A Saucerful of Secrets". The bible for the band is undoubtedly The Pink Floyd Encyclopedia, which will garner its own entry elsewhere on this site.
