Instead, they've included real stereo, original mono, and some fake stereo mixes, meaning that every song is represented twice on the same disc, all of it with high-end 24-bit remastering. There's no denying this stuff sounds spectacular, even to the untrained ear. But here's the truth of it: This is not just the Beatles as Americans first came to know them, but the early evolutionary stages of the most creative and influential musical group in post-'50s pop history. From here they would reconfigure music in frankly astonishing ways, until they took themselves too seriously and began to write down to their acolytes from a psychedelic pulpit. There's real joy in these grooves, and that's what the Fab Four was all about.
