Here, There and Everywhere, by Geoff EmerickRead about the other entries on the list.
Emerick was the sound engineer on two of The Beatles’ most popular albums, Revolver and Sgt. Pepper’s Lonely Hearts Club Band, which arrived after the band gave up live performances to focus on working in the studio. The sound of these two albums reverberates through pop music today. Emerick offers a nice balance of engineering geekery and straightforward explanation that will make you hear the music differently.
