Written over the course of a decade, the book addresses the technical side of the Beatles' sessions and was written with the assistance of many of the group's former engineers and technicians,[1] chief among them Peter K. Burkowitz, designer of the REDD mixing console.

[2] The book examines every piece of recording equipment used at Abbey Road Studios during the Beatles' sessions, including all microphones, outboard gear, mixing consoles, speakers, and tape machines.

The effects used on the Beatles' records are addressed in great detail, with full explanations of concepts such as ADT and flanging.

The "Production" section of the book looks at the group's recording processes chronologically, starting with their "artist test" in 1962 and progressing through to their final session in 1970.

[citation needed] The release of the book was celebrated in November 2006 with a party in Studio Two at Abbey Road.
