The Beatles' original 1973 compilation 1962-1966 ("Red") and 1967-1970 ("Blue") have been remastered by the same dedicated team of engineers at EMI Music's Abbey Road Studios responsible for remastering The Beatles' original UK studio albums, carefully maintaining the authenticity and integrity of the original analogue recordings. The result is the highest fidelity the catalogue has seen since its original release. Both 2CD packages include expanded booklets with original liner notes, newly written essays by Bill Flanagan and rare photos. "Red" and "Blue" are the first Beatles compilations to be released after the band's 1970 disbandment, the popular collections each feature a selection of singles and album tracks written by the band's members.
