The first in a series of three double-CD sets of previously unreleased and rare Beatles material, released in conjunction with the mammoth Anthology video documentary. This covers the late '50s to the end of 1964, mixing studio outtakes, live performances, primitive recordings from the Quarrymen/Silver Beatles days, excerpts from the famous 1962 Decca audition, the most notable 1961 Tony Sheridan-era recordings, and brief spoken bits from interviews. Although this material is undeniably of vast historical importance, it can't be placed in the same company as the Beatles' proper albums, in either cohesion or quality. While the studio outtakes (many never even heard on bootleg) are the most enticing items, these are almost exclusively alternate versions of songs they placed on their official releases (the most notable exceptions being the 1964 R&B cover "Leave My Kitten Alone," the 1962 demo "How Do You Do It," and the unimpressive 1964 Harrison original "You Know What to Do").
The final installment of the Anthology series has two discs of previously unreleased material from the White Album era through the group's demise in early 1970. In terms of sheer listenability, this may be the strongest volume of the three, if only because it focuses almost solely upon studio recordings rather than mixing live concerts/broadcasts and outtakes. Also, by this time the Beatles had perfected their approach to recording, meaning that even the early/alternate versions of many of their cuts were often of outstanding quality.
As expected, the second installment of the Anthology series reflects the Beatles' increasing use of the studio-as-laboratory during their "middle years." Some live material from 1965 to 1966 appears on the first disc, and the second "reunion" single ("Real Love") leads off the set. But the emphasis is upon alternate takes from early 1965 to early 1968, during which time the group rapidly evolved from post-Merseybeat through folk-rock to psychedelia. As with the first volume, this is nearly always interesting but perhaps thinner on revelations than some might expect. The Help!-era outtakes "If You've Got Troubles" and "That Means a Lot" are on the light side but very fun, especially the latter, which Paul and the group perform much better than P.J. Proby (who covered the song shortly afterward).
