The camaraderie among the four Beatles was at its highest throughout this period. According to Rodriguez, "Revolver" marked the first time the Beatles integrated studio technology into the "conception of the recordings they made". He views this approach as reflective of the group's waning interest in live performance before crowds of screaming fans, "in favor of creating soundscapes without limitation" in a studio environment. For the first time at EMI Studios, the company's four-track tape machines were placed in the studio's control room, alongside the producer and balance engineer, rather than in a dedicated machine room. The Beatles' new recording engineer on the project was nineteen-year-old Geoff Emerick, whom author and critic Ian MacDonald describes as an "English audio experimentalist" in the tradition of Joe Meek. Emerick recalled that no preproduction or rehearsal process took place for "Revolver"; instead, the band used the studio to create each song from what was often just an outline of a composition. Speaking shortly before the start of the sessions, Lennon said that they had considered making the album a continuous flow of tracks, without gaps to differentiate between each song.
