The Wall of Sound

The Wall of Sound (also called the Spector Sound) is a music production formula developed by American record producer Phil Spector (who died yesterday at Gold Star Studios, in the 1960s, with assistance from engineer Larry Levine and the conglomerate of session musicians later known as “the Wrecking Crew”. The intention was to exploit the possibilities of studio recording to create an unusually dense orchestral aesthetic that came across well through radios and jukeboxes of the era. Spector explained in 1964: “I was looking for a sound, a sound so strong that if the material was not the greatest, the sound would carry the record. It was a case of augmenting, augmenting. It all fit together like a jigsaw.”

Critical shorthand usually reduces the Wall of Sound inaccurately to a maximum of noise. Levine recalled how “other engineers” mistakenly thought that the process was “turning up all the faders to get full saturation, but all that achieved was distortion.” To attain the Wall of Sound, Spector’s arrangements called for large ensembles (including some instruments not generally used for ensemble playing, such as electric and acoustic guitars), with multiple instruments doubling or tripling many of the parts to create a fuller, richer tone. For example, Spector often duplicated a part played by an acoustic piano with an electric piano and a hapsichord. Mixed well enough, the three instruments would then be indistinguishable to the listener.

Among other features of the sound, Spector incorporated an array of orchestral instruments (strings, woodwind, brass and percussion) not previously associated with youth-oriented pop music. Reverb from an echo chamber was also highlighted for additional texture. He characterized his methods as “a Wagnerian approach to rock & roll: little symphonies for the kids”. The combination of large ensembles with reverberation effects also increased the average audio power in a way that resembles compression. By 1979, the use of compression had become common on the radio, marking the trend that led to the loudness war in the 1980s.

The intricacies of the technique were unprecedented in the field of sound production for popular music. According to Beach Boys leader Brian Wilson, who used the formula extensively: “In the ’40s and ’50s, arrangements were considered ‘OK here, listen to that French horn’ or ‘listen to this string section now.’ It was all a definite sound. There weren’t combinations of sound and, with the advent of Phil Spector, we find sound combinations, which—scientifically speaking—is a brilliant aspect of sound production.” Session guitarist Barney Kessel noted how “terribly simple” it was, however, “the way [Spector] recorded and miked it, they’d diffuse it so that you couldn’t pick out any one instrument. Techniques like distortion and echo were not new, but Phil came along and took these to make sounds that had not been used in the past. I thought it was ingenious.’

Perhaps Phil Spector’s most contentious use of his production techniques was on theLet it Be album. Spector was brought in to salvage the incomplete Let It Be, an album abandoned by The Beatles, performances from which had already appeared in several bootleg versions when the sessions were still referred to as Get Back. “The Long and Winding Road”, “I, Me, Mine”, and “Across the Universe” received the greatest amount of post-production work. The modified treatment (often described as a Wall of Sound, although neither Spector nor the Beatles used this phrase to refer to the production) and other overdubs proved controversial among fans and the Beatles. In 2003, Let It Be…Naked was released, an authorized version without Spector’s additions. Outside of Spector’s own songs, the most recognizable example of the “Wall of Sound” is heard on many classic hits recorded by The Beach Boys (e.g., “God Only Knows”, “Wouldn’t It Be Nice”—and especially, the psychedelic “pocket symphony” of “Good Vibrations”).
