Released today in 1971: Led Zeppelin’s untitled fourth album.

Led Zeppelin IV: The Monument That Redefined Rock

Released on this day in 1971, Led Zeppelin’s untitled fourth album—universally known as Led Zeppelin IV—remains a cornerstone of modern music. It was the record that silenced critics, redefined genres, and elevated rock into myth. Conceived in secrecy and symbolized by four mysterious runes, it was more than an album—it was an artistic statement, an act of defiance, and a sonic landmark that continues to echo across generations.

From the first bars of “Black Dog,” Robert Plant’s swaggering vocals spar with Jimmy Page’s jagged riffs in a primal call-and-response that defines hard rock bravado. Then comes “Rock and Roll,” a thunderous nod to the genre’s roots, powered by John Bonham’s unstoppable groove. “The Battle of Evermore” follows with a haunting beauty, featuring a rare guest vocal by Fairport Convention’s Sandy Denny—her duet with Plant transforming folklore into melody. And then, of course, “Stairway to Heaven” — a track so immense it transcended radio formats and became a cultural scripture, bridging mysticism and melody with breathtaking precision.

Side two proves equally formidable. “Misty Mountain Hop” pulses with rebellious energy, while “Four Sticks” experiments with rhythmic complexity and raw studio innovation. “Going to California” slows the tempo, offering a pastoral moment of reflection, with Plant’s yearning voice drifting over Page’s delicate acoustic arrangement. Finally, “When the Levee Breaks” crashes in like a flood—Bonham’s colossal drumming recorded in a stairwell to achieve that cavernous sound that would later inspire generations of hip-hop producers. It was a finale that unknowingly bridged rock and rap decades before the term “sampling” existed.

What makes IV so enduring is its perfect balance of power and nuance. The album doesn’t just showcase each member’s technical brilliance—it reveals their unity as a band at their creative peak. Page’s production, Jones’s arrangements, Plant’s poetic lyricism, and Bonham’s primal pulse come together with near-spiritual synergy. It’s not simply an album of songs—it’s a cinematic journey, a fusion of blues, folk, and metal that remains as vital today as it was half a century ago.

Over fifty years later, Led Zeppelin IV still stands as a masterpiece beyond category. It has inspired countless artists, sold over 37 million copies, and remains a benchmark of what rock can achieve when imagination, intensity, and authenticity collide. From “Black Dog” to “When the Levee Breaks,” every note feels eternal—proof that legends don’t just write songs; they carve monuments in sound.
