The Beatles hired someone to build them a new studio. According to George Harrison, the entire project was a disaster for the band.
In the late 1960s, George Martin, Paul McCartney, and George Harrison, among others, began voicing their concerns about someone working with The Beatles. “Magic” Alex Mardas was one of Apple Corps’ earliest employees and a friend of John Lennon. He promised them unique electronic decorations and improved recording equipment. The band enlisted him to build them a shiny new studio, a project Harrison later described as a complete disaster.

As an Apple employee, Mardas grew familiar with The Beatles’ recording equipment and told them it was terribly out of date. Per the book Paul McCartney: Many Years From Now by Barry Miles, Mardas began telling them he could design a seventy-two-track studio that would be more advanced than any existing studio.
