LONDON (AP) -- The entire catalog of music by The Beatles is being digitally remastered for release in September.

Apple Corps Ltd. and EMI Music say they will release the new discs Sept. 9 on the same day as the release of a video game, "The Beatles: Rock Band."

Each of the dozen new CDs will include the original U.K. album art and expanded liner notes.

Apple and EMI will also release "The Beatles in Mono" with the original monaural versions of 10 albums plus some other bits in mono.

Apple and EMI made no mention in their announcement Tuesday about plans for digital distribution.
