This is all utterly BS! The Beatles “4 tracks argument” is old, worn and misleading. The Beatles indeed recorded onto 4 track tapes but they also recorded to Mono and to 2 tracks at the beginning. The number of tracks has no relevance to the ease of the recording process, on the contrary - the fewer tracks you have the hardest the balancing act is! Try to do a mono recording of a whole band - no mix and eq late - to learn what it takes.
Moreover, the Beatles team was far from being "…with just a little talent" as one of the writers here proclaims. They had the BEST production team of their time, the best equipment and the best studio in the world, amazing array of high quality mics and a hell of talented production team - and they had one of a kind songwriting and performing ability. The Sgt. Pepper album is The Beatles and team at peak performance in all aspects; I would doubt it if a one-man operation in a bedroom studio could ever achieve such a high level of human genius.
