Led Zeppelin IV

Led Zeppelin IV (officially untitled, though commonly known by several names including "Zoso" and "Four Symbols") is the fourth studio album by Led Zeppelin, released on November 8, 1971, through Atlantic Records. It was recorded primarily at Headley Grange, a former workhouse in Hampshire, with additional sessions at Island Studios in London.^[1]

The decision to leave the album untitled was a deliberate provocation by the band, particularly Jimmy Page, who wanted the music to speak entirely for itself in response to critics who had dismissed the group as hype over substance.^[2] Each band member chose a symbol to represent themselves on the inner sleeve, with Page's "Zoso" glyph becoming the album's unofficial identifier.^[3]

The album contains "Stairway to Heaven," which became the most requested song in FM radio history despite never being released as a single.^[1] Robert Plant has described the lyrics as arriving in a near-automatic writing state, sitting by the fire at Headley Grange: "My hand was writing out the words... I just sat there and looked at them and then I almost cried."^[4]

Beyond its iconic centerpiece, the album ranges from the explosive riffing of "Black Dog" and "Rock and Roll" to the delicate English folk of "The Battle of Evermore" and the acoustic meditation of "Going to California," demonstrating a breadth that few hard rock bands of the era could match.^[2]

Led Zeppelin IV has sold over 37 million copies, making it one of the highest-selling albums in history.^[1] It is certified 24-times platinum in the United States alone. Critics who initially underrated Led Zeppelin have long since reversed course; the album now regularly appears in the top ten of all-time greatest album lists.^[5]

The record closes with "When the Levee Breaks," a reworking of a 1929 country blues single by Kansas Joe McCoy and Memphis Minnie written in the aftermath of the Great Mississippi Flood of 1927. Robert Plant, who owned the original recording, suggested it to the rest of the band while they were assembling material for the album.^[6][7]

The same Headley Grange sessions that produced "Stairway to Heaven" also produced the track's cavernous drum sound: engineer Andy Johns recorded John Bonham at the bottom of a stone stairwell with microphones suspended three stories above, then ran the result through a Binson Echorec analog delay before the band slowed the whole track down in the mix.^[8]. Along with the folk mysticism of "The Battle of Evermore" and "Going to California," it shows the album's range stretching in the opposite direction, toward a real historical catastrophe rather than myth.

That drum break has since become one of the most sampled pieces of music in popular history, turning up in recordings by the Beastie Boys, Dr. Dre, Eminem, and Beyoncé, decades after it was captured in an English stairwell.^[9]
