You’ve probably seen the thumbnail a thousand times while scrolling through Hulu or Disney+. It’s stark. High-contrast black and white. Just a legendary Beatle and a guy who looks like a barefoot wizard standing over a mixing console. On the surface, McCartney 3 2 1 feels like just another music documentary in an era saturated with them. But honestly? It’s different. It’s not a biography. It’s not a "history of the band" piece.
It is, basically, the world’s most expensive and well-lit masterclass in how to build a song.

Most people get this show wrong. They think it’s a retelling of the Liverpool-to-stardom myth. It isn’t. If you want the drama, you watch Get Back. If you want to know why a bassline in 1967 changed the way people think about rhythm, you watch this. McCartney 3 2 1 works because it ignores the gossip and focuses on the stems.
The Rick Rubin Effect: Breaking the Script
Rick Rubin is a fascinator. He doesn't interview Paul; he "geeks out" with him. Most interviewers ask Paul the same questions he’s been answering since 1964. What was John like? How did it feel to be on Ed Sullivan? Rubin doesn't care about that. Rubin wants to know why the drums on "Come Together" sound like they’re being played in a different room than the bass.
There’s this moment where Rubin pulls a fader on the console. Suddenly, the vocals vanish. The guitars are gone. All you hear is Paul’s melodic, almost lead-guitar-style bass playing on "Something."
Paul looks at the speakers like he’s hearing it for the first time.
"I'd butt in and they'd hate me for it," McCartney says, talking about his tendency to overplay. It’s a rare bit of self-awareness. He admits he was the "bossy" one. But then you hear the track isolated, and you realize that if he hadn't been bossy, the song wouldn't have that specific, driving pulse.

Behind the Black and White Aesthetic
Director Zachary Heinzerling made a bold choice here. No archival color footage. No modern-day B-roll of London streets. Just two guys in a barn-like studio in the Hamptons.
The lighting is dramatic. Harsh whites and deep blacks. It makes the wrinkles on Paul’s face and the tangles in Rubin’s beard look like a landscape. It strips away the "pop star" sheen. By removing color, the show forces you to focus on the sound.
It’s tactile.
You see Paul’s hands on the piano. He explains he can’t read or write music. Think about that. The man who wrote "Yesterday" and "Eleanor Rigby" basically navigates the keyboard by shapes. He finds "Middle C" and builds from there. It’s a "head job," as he puts it.
Why the Mixing Board is the Third Character
The heart of McCartney 3 2 1 is that console. It allows Rubin to deconstruct the "magic" that fans usually just accept as a finished product.
- They isolate the string section in "Eleanor Rigby."
- They listen to the "F-demented" chord that starts "Michelle."
- They talk about James Jamerson, the Motown bassist who gave Paul the "permission" to be more melodic on his own instrument.
Rubin acts as the proxy for every musician who has ever wondered how did they do that? He sits on the floor sometimes. He stands. He moves with the music. It’s infectious.
The Myth of the "Fifth Beatle" and Other Revelations
We’ve all heard of George Martin. We know he was the "Fifth Beatle." But in McCartney 3 2 1, Paul gives us the nuanced version. He talks about how Martin brought the classical influence, sure, but he also talks about the friction. He talks about the moments when the band pushed back.
One of the coolest stories involves the "Piccolo Trumpet" on "Penny Lane." Paul heard a guy playing it on the telly (it was David Mason playing Bach’s Brandenberg Concerto No. 2) and told George Martin he wanted that sound. Martin told him it was technically impossible to play the notes Paul wanted on that instrument.
Paul’s response? "Well, let's try."

They did. And it became one of the most iconic solos in pop history. That’s the core of the show: the refusal to accept "no" as an answer to a creative impulse.
The Lessons You Can Actually Use
If you’re a creator, a musician, or just someone who likes to know how things work, there are some pretty heavy takeaways here. This isn't just nostalgia; it's a blueprint for creative longevity.
1. Don't fear the "Mistake"
Paul talks about his guitar solo on "Another Girl" and calls it a "bold mistake." He wasn't the lead guitarist. He just "butted in." Sometimes the "wrong" person playing the "wrong" part creates the texture the song actually needs.
2. Limitations breed Innovation
The Beatles were working on 4-track and 8-track machines. They didn't have unlimited layers. They had to make decisions. They had to commit. Paul notes that because they didn't have phones or distractions, they had to write melodies that were memorable because they couldn't just record a voice memo and forget about it.
3. Collaboration requires Contrast
The show highlights the "Getting Better" dynamic. Paul sings "It's getting better all the time." John interjects "It couldn't get much worse." That tension—the optimist vs. the cynic—is what made the songs three-dimensional. Without the "worse," the "better" is just a greeting card.
Final Thoughts on the Legacy of 3 2 1
Is it perfect? No. Some of the stories are ones that hardcore fans have heard in various biographies or The Beatles Anthology. But hearing them while the master tapes are being manipulated in real-time gives them a fresh weight.
It reminds us that Paul McCartney isn't just a "celebrity." He’s a laborer of sound. He’s a guy who still gets a massive grin on his face when he hears a Ringo Starr drum fill.
If you want to understand the mechanics of the 20th century's most important music, stop looking for "hidden secrets" and just listen to the stems. The truth is right there in the faders.
What to Do Next
- Listen to "Revolver" with Headphones: After watching the show, go back to the Revolver album. Specifically, listen to the bass in "Taxman" or "Rain." You’ll hear the Motown influence Paul talks about with Rubin.
- Watch for the "Waterfalls" Segment: Many people skip the solo era talk, but the breakdown of "Waterfalls" from McCartney II shows how his experimental side never really left, even after the Beatles.
- Check the Credits: Look up Zachary Heinzerling’s other work. His eye for intimacy is what makes this feel less like a TV show and more like a private conversation you weren't supposed to hear.
The series is a short watch—six episodes, all around 30 minutes. It’s the perfect length for a weekend binge that actually leaves you feeling smarter than when you started.
