Before Pink Floyd became the stadium-filling, progressive rock juggernaut of the 1970s, they were a rogue collective of art-school visionaries spearheading London’s underground psychedelic movement. At the absolute epicenter of this sonic revolution was Roger Keith “Syd” Barrett. With his unmatched charisma, whimsical storytelling, and innovative slide-guitar techniques, Barrett was the undisputed engine of the band’s early identity.
Yet, the very year that brought Pink Floyd their mainstream breakthrough also delivered the catalyst for Barrett’s tragic psychological decline. In the lore of classic rock, one specific 1967 song stands as the definitive, heartbreaking turning point—the moment the “Crazy Diamond” began to fracture.
That song was “See Emily Play.”
The Birth of a Psychedelic Masterpiece
Fresh off the minor success of their debut single “Arnold Layne” earlier that spring, Pink Floyd entered Sound Techniques Studio in Chelsea, London, on May 21, 1967, to record its follow-up. Produced by Norman Smith, the sessions for “See Emily Play” were a masterclass in avant-garde pop construction. The track utilized sped-up piano bridges, backwards tape loops, heavy echoes, and Barrett’s distinctive technique of using a plastic ruler or a Zippo lighter to create an otherworldly slide-guitar effect.
Thematically, the song was shrouded in Barrett’s trademark mystical whimsy. Syd claimed the composition was inspired by a hallucinatory vision of a young girl he saw sleeping in the woods after an LSD trip. In reality, the track was largely an ode to a 15-year-old regular at the UFO Club named Emily Young—nicknamed the “psychedelic schoolgirl”—who would frequently dance in long, Victorian-style gowns.
On paper, the track was a flawless distillation of the impending Summer of Love. But inside the studio walls, a darker reality was beginning to take shape.
The Chilling Studio Visit
During those intense May recording sessions, a young guitarist from Cambridge named David Gilmour dropped by the studio. At the time, Gilmour was not yet a member of Pink Floyd; he was simply a close childhood friend of Barrett’s who wanted to see how the band’s new record was coming along.
What Gilmour encountered when he walked through the doors of Sound Techniques shocked him to his core. The vibrant, chatty, and fiercely intelligent friend he had grown up with was gone. In his place sat a man with vacant, detached eyes who stared right through Gilmour, seemingly unable to recognize or acknowledge his oldest companion. The sudden, severe toll of heavy, recreational LSD use combined with the mounting anxiety of sudden fame had fundamentally altered Barrett’s brain chemistry.
Reflecting on that devastating studio encounter years later, Gilmour pointed to that exact session as the definitive line between the old Syd and the tragedy that followed.
“I’ll go on record as saying that was when he changed,” Gilmour later stated with haunting finality.
The Cost of Success
Despite the unsettling atmosphere behind the scenes, “See Emily Play” was officially released on June 16, 1967. It instantly struck a chord with the British youth, rapidly climbing the charts to become a definitive UK Top 10 hit.
With a hit single came the unrelenting machinery of the commercial music industry. Throughout July 1967, Pink Floyd was booked to perform the song three separate times on the BBC’s flagship television show, Top of the Pops. It was during these televised appearances that Barrett’s erratic behavior became public property. He appeared on stage visibly disheveled, catatonic, and entirely uncooperative, at one point actively refusing to mime his vocals.
Barrett deeply resented the commercial expectations thrust upon him, expressing a profound fear of being packaged as a conventional pop star. Producer Norman Smith noted that Syd’s subsequent protests against his own success were rooted in a fierce defense of his artistic integrity, but the psychological damage was already done. The pressure cooker of mainstream stardom only accelerated his retreat inward.
A Haunting Legacy
By early 1968, Barrett’s state had deteriorated to the point where he could no longer function as a live performer. The band quietly brought David Gilmour into the fold to cover Barrett’s guitar parts, before ultimately parting ways with their founding frontman in April of that year.
“See Emily Play” remains one of the crown jewels of 1960s psych-pop, but its legacy is inextricably bound to the ghost of the man who created it. Decades later, when Pink Floyd recorded their sprawling tribute to Barrett, “Shine On You Crazy Diamond” for the 1975 album Wish You Were Here, keyboardist Richard Wright snuck a subtle, heartbreaking nod into the track’s final seconds. As the song fades out, Wright softly plays the familiar, floating organ notes of “See Emily Play”—a quiet, final salute to the exact moment the light in Syd Barrett’s eyes went out forever.
