In the second half of our brief overview of how George Martin and The Beatles used multitrack recording, we’ll hear how they pushed four-track recording to its breaking point, and we’ll learn how they managed the complex arrangements on Sgt Pepper with such limited means. We’ll also hear how the band’s jump to eight-track recording during the White Album sessions reflected a shift in their relationship with their producer, and how they were still pushing the limits of recording technology even on their last album.
