Led Zeppelin IV at 55: The Untitled Album That Said It All

Fifty-five years ago this week, rock's biggest band released an album with no title, no band name and not a single word on its cover. On November 8, 1971, Atlantic Records put out Led Zeppelin's fourth album, and the only clues on the sleeve were an old man hauling sticks and four mysterious hand-drawn symbols. It looked like career sabotage. It became one of the best-selling records ever made.

A Fourth Album With Something to Prove

By late 1970, Led Zeppelin had a chip on its shoulder. Led Zeppelin III, with its acoustic detours, had drawn a lukewarm and sometimes baffled response from critics, and Jimmy Page decided the next record would speak for itself. Atlantic pushed back hard, and a press agent reportedly warned that disappearing for a year and then releasing a nameless album would be career suicide. The band refused to hand over the master tapes until the label agreed to do it their way.

Instead of a title, each member picked a personal emblem. Page designed his own, the famous squiggle fans read as "ZoSo," though he never explained what it means and has said it was never meant to be a word. John Paul Jones and John Bonham chose theirs from a reference called The Book of Signs, while Robert Plant drew a feather inside a circle. That's why fans also call it Four Symbols or Zoso.

Tea, Gardens and a Mobile Studio

Most of the album took shape at Headley Grange, an old house in Hampshire, England, where the band used the Rolling Stones' Mobile Studio and recorded whenever inspiration struck. "Black Dog" was named for an aging black Labrador who wandered the grounds during the sessions. Page picked up Jones's mandolin, an instrument he had barely touched, and came out with "The Battle of Evermore," a duet featuring Fairport Convention's Sandy Denny. A frustrated Bonham grabbed two pairs of drumsticks to nail "Four Sticks."

Then there's side one's centerpiece, "Stairway to Heaven," eight minutes building from acoustic guitar and recorders to a roaring finale. The band resisted every push to release it as a single, and FM radio played it endlessly anyway. The album closes with a crushing reworking of "When the Levee Breaks," a blues first recorded by Memphis Minnie and Kansas Joe McCoy in 1929, and Bonham's colossal drum sound on it still turns heads today.

A Collector's Puzzle Box

The original LP rewards a close look. There's no printing at all on the front or back covers, and not even a catalog number on the spine. The weathered picture of the stick-carrier was a find Plant made at an antique shop, and it was hung on the papered wall of a half-demolished house for the cover shot; flip it over and a modern Birmingham tower block stares back. Open the gatefold and you'll find "The Hermit," an illustration based on the tarot card of the same name. Check the inner sleeve, too: Sandy Denny got a small fifth symbol of three triangles, and the "Stairway" lyrics are set in an ornate typeface Page adapted from a 19th-century arts and crafts magazine.

Fifty-five years on, the gamble looks like genius: Led Zeppelin stripped away everything but the music, and the music carried it. With roughly 37 million copies sold worldwide, it remains the band's biggest seller and a rite of passage for every generation that drops the needle on side one.
