Title: competent but unbalanced
Review: Kozinn's book is a competent summary of the Beatles performance and recording career, and is refreshingly calm and balanced in its discussion of the causes for the Beatles' disbanding. It's a safe book for the relatively uninformed to read. But it fails in its stated intention of getting at the "mechanisms" of the Beatles' innovative genius. Although Kozinn is genuinely appreciative of Lennon's genius, the book commits the common sin of dismissing McCartney's contributions as a sort of idiot savant knack for commercial melodies. Without getting more than about 20% McCartney into the Lennon-McCartney mix, you really can't get a grip on the songbook or the remarkable recording revolution these two young men were responsible for. A more accurate title would have been "John Lennon and Other Musicians."
