I have read a fair few Floyd books now including Nick Masons and i have to say this is by far and away the best and most comprehensive. It starts right back at the begining in the mid 60's right through to 2007, covering literally everything. It also covers their solo ventures during and after Floyd and also gives great info on how all the albums faired in the US and the UK (Solo's included). He must have been working on this book for years. I was very impressed that he mentioned Dave Gilmour turned up on Michael Parkinsons chat show in 1999 as a session guitarist for Paul McCartney who was having a full show dedicated to him. Dave Gilmour was never mentioned on the show and i only noticed myself that he was there playing. Very impressive research. I learn't a lot about the band and its members that i never knew and will have to read it again as its hard to remember everything. Its a great story and also quite sad (Syd's decline). Roger Waters comes out of it the worst, looks like he gave Gilmour a very hard time and the rest of the band also. His ego and tempermant being his main problem. And considering the abuse he has taken, Dave Gilmour comes out of it with dignity in tact.
If your a Floyd fanantic or a casual music listener with a passing interest in the band, its a must buy.
