Ken Townsend

• 1. Introduction

  ›

  Ken Townsend stood in on the 6th of June 1962, the date the Beatles opened their account at EMI Studios. He was still on hand in August 1969, when the same four musicians wrapped work on the album Abbey Road. Townsend never picked up an instrument or stepped in front of a microphone during any of it. Engineering was his craft inside that building for his entire working life.

  What was his actual job, day to day, across all the years between that first session and the last? And what did he do to the sound itself that nobody else in the room could have done?

• 2. The Backroom Boys

  A four-year apprenticeship at EMI's Hayes facility came before anything else. Townsend joined EMI Studios as a recording engineer in 1954. He stayed with the Beatles for the whole of their time at EMI, including work on Rubber Soul and Sgt. Pepper's Lonely Hearts Club Band.

  George Martin later called Townsend and colleagues like him one of the studio's "backroom boys." The label fit. Townsend rarely worked directly with the band. Instead he worked as a maintenance engineer, helping build many of the studio inventions the Beatles were first to use.

  By 1974, Townsend had been promoted to the studio's general manager, and he began reshaping its identity around its connection to the Beatles. That effort reached its conclusion in 1976, when EMI Studios was officially renamed Abbey Road Studios, a title Townsend himself oversaw. He remained with the company until 1995, retiring as Chairman of the Studio Group.

  One tool built inside that studio in 1966 would change how doubled vocals sounded for good.

• 3. Inventing Artificial Double Tracking

  ›

  During the recording of "Tomorrow Never Knows," John Lennon said he was tired of singing a second take just to thicken his own vocal sound. Townsend, the studio's technical manager at the time, answered the complaint directly. He tapped the signal from the playback head and the recording head, then delayed one slightly to create two sound images from a single voice. That solution became the studio's first automatic double tracking system. Staff at the studio called it ADT.

  Townsend found that changing the delay's speed and frequency produced a range of other effects. The band used those variations throughout the recording of Revolver.

  A fix built to spare Lennon a second vocal take ended up reshaping sounds across the rest of Revolver, not just his own voice.
