Falling squarely between the 71-track triple-disc Chess Box and numerous single-album distillations of Chuck Berry's hits, most notably The Great Twenty-Eight, is this 2000-released, chronologically compiled double-disc set. Its 50 tunes include all of Berry's seminal Chess hits plus key album tracks like "Beautiful Delilah," "Jo Jo Gunne," and "Jaguar & Thunderbird" that were influential but never cracked the charts. The 20-page booklet features a fascinating, extensive essay that provides crucial insights into Berry's work as well as rare pictures and track-by-track personnel listing. Since virtually all of Berry's essential work was done for the Chess label, now part of the Universal empire, there's no reason to decry the lack of anything from Berry's Mercury years, even though those tracks are now owned by the same company and could have been included, especially tacked onto disc two that times out at a relatively conservative 64 minutes. But with a lineup like this, who's complaining? Berry is the undisputed father of rock & roll and his music, much of it blues based and in a few cases like "Havana Moon" even Caribbean inspired, remains timeless as well as inspirational decades after it was recorded. The joys of discovering forgotten, relatively obscure cuts like "Come On" or "I'm Talking About You," both of which are easily on par with any of his more popular hits, is one of life's little bonuses. Berry's lyrics remain intriguingly descriptive, and the remastered sound brings these songs alive with every instrument, especially Willie Dixon's dynamic, jazzy stand-up bass clearly defined. The savvy track selection makes this a better, more consistent listen than the bulky box and stands as the best introduction to one of the most significant pop musicians of 20th century music and the single most important rock & roller ever.
