It may seem like there's little sand left to sift through, but a new Disney+ documentary proves that there is an endless summer's worth of Beach Boys stories to uncover.

While the legendary group is so woven into the fabric of American culture  that it’s easy to forget just how innovative they were, a recently-released documentary aims to remind. The Beach Boys uses a deft combination of archival footage and contemporary interviews to introduce a new generation of fans to the band.

The documentary focuses narrowly on the first 15 years of the Beach Boys’ career, and emphasizes what a family affair it was. Opening the film is a flurry of comments about "a certain family blend" of voices, comparing the band to "a fellowship," and crediting the band’s success directly to having been a family. The frame is apt, considering that the first lineup consisted of Wilson brothers Brian, Dennis, and Carl, their cousin Mike Love, and high school friend Al Jardine, and their first manager was the Wilsons’ father, Murry.

All surviving band members are interviewed, though a very frail Brian Wilson — who was placed under a conservatorship following the January death of his wife Melinda — appears primarily in archival footage. Additional perspective comes via musicians and producers including Ryan Tedder, Janelle Monáe, Lindsey Buckingham, and Don Was, and USC Vice Provost for the Arts Josh Kun.

Thanks to the film’s tight focus and breadth of interviewees, it includes memorable takeaways for both longtime fans and ones this documentary will create. Read on for five takeaways from Disney+'s The Beach Boys.

Family Is A Double-Edged Sword

For all the warm, tight-knit imagery of the Beach Boys as a family band,  there was an awful lot of darkness at the heart of their sunny sound, and most of the responsibility for that lies with Wilson family patriarch Murry Wilson. Having written a few modest hits in the late 1930s, Murry had talent and a good ear, and he considered himself a largely thwarted genius.  

When Brian, Dennis, and Carl formed the Beach Boys with their cousin Mike Love and friend Al Jardine, Murry came aboard as the band’s manager. In many respects, he was capable; his dogged work ethic and fierce protectiveness helped shepherd the group to increasingly high profile successes. He masterminded the extended Wilson family call-in campaign to a local radio station, pushing the Beach Boys’ first single "Surfin’" to become the most popular song in Los Angeles. He relentlessly shopped their demos to music labels, eventually landing them a contract at Capitol Records. He supported the band’s strong preference to record at Western Recordings rather than Capitol Records’ own in-house studio, and was an excellent promoter. 

Murry Wilson was also extremely controlling, fining the band when they made mistakes or swore, and "was miserable most of the time," according to his wife Audree. 

Footage from earlier interviews with Carl and Dennis, and contemporary comments from Mike Love make it clear that Murry was emotionally and physically abusive to his sons throughout their childhoods. He even sold off the Beach Boys’ songwriting catalog without consulting co-owner Brian, a moment that Brian’s ex-wife Marilyn says he felt so keenly that he took to his bed and didn’t get up for three days. 

Murry Wilson was at best a very complicated figure, both professionally jealous of his own children to a toxic degree and devoted to ensuring their success. 

"Be My Baby" and The Wrecking Crew Changed Brian Wilson’s Life

"Be My Baby," which Phil Spector had produced for the Ronettes in 1963, launched the girl group to immediate iconic status. The song also proved life-changing for Brian. On first hearing the song, "it spoke to my soul," and Brian threw himself into learning how Spector created his massive, lush Wall of Sound. Spector’s approach taught Brian that production was a meaningful art that creates an "overall sound, what [the listeners] are going to hear and experience in two and a half minutes."

By working with The Wrecking Crew — a truly motley bunch of experienced, freewheeling musicians who played on Spector’s records and were over a decade older than the Beach Boys — Brian’s artistic sensibility quickly emerged. According to drummer Hal Blaine and bassist Carol Kaye, Brian not knowing what he didn’t know gave him the freedom and imagination to create sounds that were completely new and innovative. 

Friendly Rivalries With Phil Spector & The Beatles Yielded Amazing Pop Music

According to popular myth, the Beach Boys and the Beatles saw each other exclusively as almost bitter rivals for the ears, hearts, and disposable income of their fans. The truth is more nuanced: after the initial shock of the British Invasion wore off, the two groups developed and maintained a very productive, admiration-based competition, each band pushing the other to sonic greatness. 

Cultural historian and academic Josh Kun reframes the relationship between the two bands as a "transatlantic collaboration," and asks, "If they hadn’t had each other, would they have become what they became?" Could they have made the historic musical leaps that we now take for granted?

The release of Rubber Soul left Brian Wilson thunderstruck. The unexpected sitar on "Norwegian Wood," the increasingly mature, personal songwriting, all of it was so fresh that "I flipped!" and immediately wanted to record "a thematic album, a collection of folk songs." 

Brian found life on the road soul-crushing and terrifying, and was much more content to stay home composing, writing, and producing. With the touring band out on the road, and with a creative fire lit under him by both the Beatles and Phil Spector’s Wall of Sound, he had time to develop into a wildly creative, exacting, and celebrated producer, an experience that yielded the 1966 masterpiece, Pet Sounds.

Pet Sounds Took 44 Years To Go Platinum

You read that right: Pet Sounds was a flop in the U.S. upon its release. Even after hearing radio-ready tracks like "Wouldn’t It Be Nice?" and "Sloop John B" and the ravishing "God Only Knows," Capitol Records thought the album had minimal commercial potential and didn’t give it the promotional push the band were expecting. Fans in the United Kingdom embraced it, however, and the votes of confidence from British fans — including Keith Moon, John Lennon, and Paul McCartney — buoyed both sales and the Beach Boys’ spirits.  

In fact, Lennon and McCartney credited Pet Sounds with giving them a target to hit when they went into the studio to record the Beatles’ own next sonically groundbreaking album, Sgt. Pepper’s Lonely Hearts Club Band. As veteran producer and documentary talking head Don Was puts it, Brian Wilson was a true pioneer, incorporating "textures nobody had ever put into pop music before." The friendly rivalry continued as the Beatles realized that they needed to step up their game once more.

Meanwhile, Capitol Records released and vigorously promoted a best-of album full of the Beach Boys’ early hits, Best Of The Beach Boys. The collection of sun-drenched, peppy tunes was a hit, but was also very out of step with the cultural and political shifts bubbling up through the anti-war and civil rights movements of the era. Thanks in part to later critical re-appraisals and being publicly embraced by musicians as varied as Questlove and Stereolab, Pet Sounds eventually reached platinum status in April 2000, 44 years after its initial release.

Dennis Wilson Was The Only Truly Beachy Beach Boy

Although the Beach Boys first made a name for themselves as purveyors of "the California sound" by singing almost exclusively about beaches, girls, and surfing, the only member of the band who really liked the beach was drummer Dennis Wilson.

Al Jardine ruefully recalls that "the first thing I did was lose my board — I nearly drowned" on a gorgeous day at Manhattan beach. Dennis was an actual surfer whose tanned, blonde good looks and slightly rebellious edge made him the instant sex symbol of the group. In 1967, when Brian’s depression was the deepest and he relinquished in-studio control of the band, Dennis flourished musically and lyrically. Carl Wilson, who had emerged as a very capable producer in Brian’s absence, described Dennis as evolving artistically "really quite amazingly…it just blew us away."

Dennis was also the only Beach Boy who participated meaningfully in the counterculture of the late 1960s, a movement the band largely sat out of, largely to the detriment of their image. He introduced the band to Transcendental Meditation — a practice Mike Love maintains to this day — and was a figure in the Sunset Strip and Laurel Canyon music scenes. Unfortunately, he also became acquainted with and introduced his bandmates to Charles Manson. Manson’s true goal was rock stardom; masterminding the gruesome mass murders that his followers perpetrated in 1969 was a vengeful outgrowth of his thwarted ambition. 

The Beach Boys did record and release a reworked version of one of Manson’s songs, "Never Learn Not To Love" as a B-side in 1968. Love says that having introduced Manson to producer Terry Melcher, who firmly rebuffed the would-be musician, "weighed on Dennis pretty heavily," and while Jardine emphatically and truthfully says "it wasn’t his fault," it’s easy to imagine those events driving some of the self-destructive alcohol and drug abuse that marked Dennis’ later years. 

The Journey From Obscurity To Perennially Popular Heritage Act

The final minutes of The Beach Boys can be summed up as "if all else fails commercially, release a double album of beloved greatest hits." The 1970s were a very fruitful time for the band creatively, as they invited funk specialists Blondie Chaplin and Ricky Fataar to join the band and relocated to the Netherlands to pursue a harder, more far-out sound. Although the band were proud of the lush, singer/songwriter material they were recording, the albums of this era were sales disappointments and represented a continuing slide into uncoolness and obscurity.

Once again, Capitol Records turned to the band’s early material to boost sales. The 1974 double-album compilation Endless Summer, comprised of hits from 1962-1965, went triple platinum, relaunching The Beach Boys as a successful heritage touring act. A new generation of fans — "8 to 80," as the band put it — flocked to their bright harmonies and upbeat tempos, as seen in the final moments of the documentary when the Beach Boys played to a crowd of over 500,000 fans on July 4, 1980. 

While taking their place as America’s Band didn’t do much to make them cool, it did ensure one more wave of chart success with 1988’s No. 1 hit "Kokomo" and ultimately led to broader appreciation for Pet Sounds and its sibling experimental albums like Smiley Smile. That wave of popularity has proven remarkably durable; after all, they’ve ridden it to a documentary for Disney+ nearly 45 years later.
