Revisiting The Sonic Terrain of Sgt. Pepper

The Beatles’ Sgt. Pepper was recorded on a primitive analog four-track system far removed from today’s digital recording technology. Many factors came together that allowed the album to take such a unique form. For starters, it was the first time the Beatles were able to take a break from touring so as to focus only on recording. The studio itself became another instrument for The Beatles to use, and, working with producer George Martin and engineer Geoff Emerick, the production became as colorful as the songs themselves.

We spoke to several luminaries in the music world about the recording of the album, including:

Al Schmitt (engineer-producer; Bob Dylan, Paul McCartney, Frank Sinatra)
Steve Lukather (guitarist-songwriter; Toto, Ringo’s All-Starr Band)
Nancy Wilson (guitarist-songwriter, Heart, Roadcase Royale)
Bob Ezrin (engineer-producer; Alice Cooper, Pink Floyd)
Ed Cherney (engineer-producer-mixer;  Brian Wilson, Rolling Stones, Eric Clapton
Butch Vig (producer; Nirvana, Foo Fighters)
Al DiMeola (legendary jazz guitarist)

Here’ what they had to say:

Bob Ezrin: It was the first time we truly understood the studio as a powerful instrument of composition, and not just a soundproof place that captured performances. Suddenly, those of us who were making music realized that there was a higher plane of expression available to us through creative use of technology.

Nancy Wilson:  [The Beatles] were essentially inventing multi-track recording. They were so at the drawing board and creating something completely new that had never happened before. George Martin was a genius, and their muse, because he was not afraid to try all the crazy, insane, impossible things they wanted.

Ed Cherney: Before that, you had a lot of guys out in the room, and your mission was to recreate what happened out in the room. This was different. This was about bending reality, and trying to make a different dimension out of it. The first time we heard that and realized there was a studio, it opened my eyes. My goodness, there is a whole other artform to how they do that.

Bob Ezrin: It made me think of the studio as an instrument of magic.  I never wanted to be a recordist, just capturing people’s performances.  I always wanted to be a sorcerer, creating larger than life experiences from just music and sound.  

Butch Vig: Everyone involved was at the top of their game: George Martin kept raising the bar with production and arrangements; Emerick was pushing the envelope with his groundbreaking engineering prowess, and The Beatles were really hitting their peak.

Ed Cherney:
The Beatles created Sgt. Pepper knowing they would never have to perform it live, and they used that freedom as an opportunity to go beyond people’s expectations. We came from “How Much Is That Doggy In The Window,” in a very short time, to this. It was a spectacular leap in terms of artistry and courage.

Butch Vig: In this digital day and age, it is absolutely amazing to think that it was recorded on 4-track.

Ed Cherney:  Using a 4-track, they would record three tracks of information, and then bounce those to the fourth track to open up more tracks. So they were constantly bouncing and mixing between the two. It’s an engineering tour-de-force by Geoff Emerick. 

Al DiMeola
: Emerick and other Abbey Road technicians were masters at the transfer of tracks, the bounce. You have to bounce them at the highest level with no distortion, and that can’t be undone. And they did that masterfully.    

Al Schmitt: Normally when you record on 4-track tape and do many bounces, you start to accumulate a lot of hiss. You have to have the balances perfect. Once you bounce it over and add something else, you cannot re-do it. This was amazing to us; we weren’t sure how Emerick did it.

Bob Ezrin: Once something got bounced into the main master, it would have been a long way back to undo it.  So they were forced to experiment first, and then decide on what worked and what didn’t with every step they took along the way.  

Al DiMeola: Afforded the luxury of not having to go on the road, their daily job was going to the studio every day. Imagine having that wonderful gift. Not one other group could do that.  That extra time allotted in the studio, without the pressures of the road, allowed them to experiment with sounds, to take music to another level, to places we have never heard before.

Nancy Wilson: They could not have done Sgt. Pepper while they were on tour still. When you are on the road, it is really hard to get to that elated place you need to be to make good records. It is exhausting. They had to get away from the insanity, the screaming hordes everywhere. So they wisely stepped off the road into the studio for the purpose of exploring and bringing all those masses along with them. They knew they had the ear of the world, so they worked their art really hard to bring something authentic and refreshing and new.

Ed Cherney:
Because it was recorded on 4-track, that means that all their performances were great from top to bottom. The solos, the vocals, every note, every performance, it all had to be perfect and not pieced together like we do now. I don’t know how they did it, but it affected me profoundly.

Al DiMeola:
I always reflect on the enormity of the sound, largely due to the big analog sound of the four-track. When you record an acoustic guitar analog, it sounds big and has presence. The less tracks, the wider the space of the tape, the fatter the sound.  Analog has a much punchier, fatter sound. Listen to the cello. There is no way anyone is going to get a cello sound that big. Or the way John’s voice sounds like it is right there with you, that big.     

Bob Ezrin:
The medium gave them infinite possibilities. But it also required that they craft each part and performance to play its particular role in their overall concept. It meant having a clear intention for each song before starting out and then only committing to things that actually made the song work.

Ed Cherney:
The technology at the time sounded astounding. A lot of the equipment was hand-made, and had a specific sound that was rich and full. They got the low end to speak in a way we never heard the low end speak before. They stretched the technology more than anyone has before. I never heard drums or rhythm like that, and the bass so clear, and have it musically feel so good.

Al Schmitt:
It gave me the idea that you can try anything. Whatever worked. That was the thing that got me so much, that they experimented and picked the best of what they did. It changed the way we thought about things.

Butch Vig:
I have referenced the production ideas on Sgt. Pepper many times, consciously or unconsciously. There were so many groundbreaking studio tricks they used that are still relevant today.

Ed Cherney: In my own work, I try to fill the speakers like they did. Also, every four bars, there’s some event. You never got bored. There was always a surprise. No matter how many times you listened to it, there was something else to get your attention, to keep you entertained and to keep you in the music and the moment.  It could be a tambourine coming in, it could be a wah-wah. There was always something, and you were never bored listening.

Steve Lukather: Once they gave up playing live, they knew they could do anything, because they didn’t have to perform it live. They created a new style of record making. They took the studio seriously. They were pros, and they wanted to get it right. They had an idea and they had George Martin and Geoff Emerick there to help them make it real, to realize the ultimate vision of it all. They pushed their creativity to beyond what had ever been thought of before.

Al Schmitt: I listen to it today, and it still sounds as amazing as ever, if not more. The sound of the thing – the sonics themselves – still absolutely thrill me. The magic of Sgt. Pepper is forever.
