The Beatles’ original 1973 compilations, 1962-1966 (‘Red’) and 1967-1970 (‘Blue’) have been digitally remastered for worldwide CD release on October 18 (October 19 in North America).

 

The first Beatles compilations to be released after the band’s 1970 disbandment, the popular ‘Red’ and ‘Blue’ collections each feature a selection of singles and album tracks written by the band’s members.

 

‘Red’ and ‘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.

I remember buying the original releases, I still own a blue vinyl copy of 1967-1970. I had a casette version of 1962-1966, but gave it to a friend a long time ago and never got it back.

I've got a blue vinyl version as well somewhere then I got both on CD when they came out.
