To continue the Beatlesfest:
Anthology, volumes 1, 2 & 3. The covers, by Klaus Voormann who did the Revolver cover, make a single poster when lined up:

Here you have recordings starting with The Quarrymen in 1958, home demos in 1960, Hamburg clubs, some of the Decca audition, TV shows - and then loads of studio outtakes, ending with the last studio session in 1970. Also several songs that appeared later on solo albums (e.g. Junk, My Sweet Lord), and a couple of later John Lennon demos turned into "Beatles" tracks by the other three in 1994.
