5 Surprising Facts About Led Zeppelin’s ‘In Through the Out Door’

By 1979, Led Zeppelin were both battered and brilliant. Out of exile, grief, and excess came In Through the Out Door — an album recorded in Stockholm that blended samba rhythms, synth experiments, and smoky barroom blues into a strangely forward-looking final chapter.

1. The ABBA Connection
The album was recorded at ABBA’s Polar Studios in Stockholm, a space more associated with shimmering pop than heavy rock. Zeppelin turned it into their own laboratory, with John Paul Jones’ Yamaha GX-1 synthesizer coloring tracks like “Carouselambra” in ways that felt futuristic.

2. Six Hidden Covers
The sleeve design was a trickster’s delight. Each copy came wrapped in a plain brown paper bag, hiding one of six alternate bar-room photo covers. Fans had no idea which version they owned until peeling the wrapping, turning every purchase into a lucky dip for collectors.

3. Samba Meets Shuffle
“Fool in the Rain” drew inspiration from the samba rhythms Plant had absorbed during the 1978 World Cup broadcasts. The result — Bonham’s Purdie shuffle colliding with carnival swing — was one of the band’s most surprising rhythmic left turns, and their last US hit single.

4. A Song for Karac
“All My Love” was Robert Plant’s tribute to his late son Karac. Co-written with Jones, the song’s tender heart is marked by a classically-styled synth solo. For a band known for thunder, this ballad stood as one of their most openly vulnerable moments.

5. A Puzzle of Perspectives
The Hipgnosis artwork told its own story: a man burning a Dear John letter in a New Orleans-styled bar, observed by six others. Each of the six covers offered a different perspective of the same scene — a clever nod to fractured viewpoints within the band itself.

In Through the Out Door stands as both a swan song and a bold experiment, filled with synths, samba grooves, and one last blast of Zeppelin grandeur. Wrapped in brown paper mystery and recorded far from home, it captured a band still chasing new sounds on the edge of their story.
