In celebration of its 60th anniversary on August 5, we are reflecting on the enduring legacy of The Beatles’ Revolver. Among its many innovations, the album’s closing track, “Tomorrow Never Knows,” stands as a monumental shift in the trajectory of popular music.
The song famously appeared in the fifth season of Mad Men, where Megan Draper introduces her husband, Don, to the track. As the music shudders to life, it serves as a sonic backdrop to the characters’ existential anxieties—a fitting use for a song that explores themes of ego death and the cyclical nature of time. For viewers in 2012, the song was a known psychedelic landmark; for the characters in the show, it was a jarring, futuristic intrusion into their mid-century reality.
The Birth of a Psychedelic Masterpiece
The Beatles did not need “Tomorrow Never Knows” to make Revolver a watershed moment, but the track undeniably obliterated the barriers of their established sound. While tracks like “Eleanor Rigby” and “Love You To” showcased the band’s growth, “Tomorrow Never Knows” was something entirely different. Inspired by Timothy Leary’s The Psychedelic Experience, John Lennon sought to capture the essence of a psychedelic trip, utilizing tape loops, flanged instruments, and reversed sounds to create a sonic maelstrom that felt beamed from another dimension.
The recording process was as experimental as the result. Ringo Starr provided tumbling, hypnotic drums, while George Harrison contributed sitar textures, and Paul McCartney helped construct eerie seagull-like sounds from sped-up studio laughter. It was a radical departure from the pop hits that had defined the band only a few years prior.
A Legacy of Constant Refraction
Sixty years later, the song plays like a rabbit hole of refractions. It challenges our perception of avant-garde art and the way we consume history. In an era where digital culture allows us to access almost any sound from the past, we often find ourselves in a feedback loop, constantly recontextualizing the breakthroughs of 1966. The song’s instruction to “turn off your mind, relax and float downstream” feels both like a relic of the counterculture and a timeless meditation on the nature of existence.
As we look toward the future of music—an era increasingly defined by AI and the endless recycling of past genres—the audacity of “Tomorrow Never Knows” remains a benchmark. It reminds us that true innovation often comes from stepping into the unknown, rather than simply rearranging the library of what has already been created. While we may feel the weight of nostalgia, the song continues to invite us to look toward the unseen horizons, just as it did for listeners six decades ago.
