All 13 original Beatles albums from the UK are remastered stereo version. Together with the 13 albums (from Please Please Me through Let It Be), the Past Masters collection is also remastered. What’s Past Masters? It has released a collection of songs by the Beatles in the 1960s, which were never recorded on their albums. These big hits like “Hey Jew” and the fast version of “Revolution belong,” which were released as a single, but not all of its 13 official studio albums.
Stereo Box Set
The remastered stereo versions of these 13 studio albums along with the Past Masters CD-ROM are all included in the stereo box. There are also lots of additional extras in this field, such as a DVD which includes a short documentary about the creation of each album.
Mono Box Set
Until about 1968, the mono-standard. This means that the stereo mix done up to that time were mostly in retrospect. It was actually the mono versions of these albums, the Beatles and George Martin spent most of his time trying to perfectly preserved, and it is for this reason that (a lot of Beatles purists, the mono versions are the “real” versions of these albums up about The White Album, was the last mixed in mono.)
For the first time these original mono mixes will be released on CD (previously they were only on original vinyl!) But these mono versions of the albums are not available and sold separately, but contains only a part of the mono-box to all 10 by The Beatles studio albums that were originally mixed in mono (ie, no Yellow Submarine, Abbey Road or Let It Be.) It also contains a CD entitled Mono Masters, which is how the corresponding Past Masters exception (of course) ie in mono. Most of the songs on Past Masters were originally mixed in mono, so this is useful.
