This book differs from nearly all of the other first eleven in this series in that instead of involving a detailed look at the songs and the music involved, given the artistes involved here are the Beatles, the author wisely focuses on the history around the recordings instead.
In so doing, Matteo has produced a little gem. Working chronologically he covers how and why the recordings occurred starting with the sessions at the Twickenham sound stage and the possible idea of a live concert at a site in North Africa to follow, progressing to the subsequent recordings made at the new Apple Studios aimed at avoiding the controls of Abbey Road, and the final Saville Row rooftop concert. The book closes with the consequences of how under different producers the incomplete recordings fell into limbo to be "rescued" by Phil Spector and the subsequent history of numerous bootleg tapes from the sessions, culminating in the release of "Let it be...Naked", a missed opportunity in the author's eyes.
What Matteo does in this story telling is include a lot of factual evidence from the thorough research he has done through interviews for the book (but it seems with none of the Beatles) and technical data garnered from many other books. But more importantly he also demyths a lot of prior held mis-perceptions along the way. His covering of the growing disillusionment of Harrison and Martin as the sessions devolve into chaos offsets the more well known stories of Ono and McCartney outbursts. From all the evidence presented, the different sessions were not the gloom and doom often conveyed subsequently especially through the released film and individual Beatles retrospective comments. Despite the growing apart that had started when recording the White Album amongst band members and Lennon's growing drug problems, a high level of fun and the sheer level of songs recorded and tested, including many that surfaced later on "Abbey Road" and solo albums is testament to the creativity that was still occurring.
The two biggest new truths for me after reading the book, are that the maligning of Allen Klein due to his business practices may have been warranted in part but are offset by the simple fact that the financial disciplines he introduced at Apple probably saved the Beatles from individual financial ruin, and that given all the hard evidence on show that this group would not stay together, the subsequent Abbey Road" recording stands as a truly iconic finale and group effort.
