In 1971, Led Zeppelin released an album with no title and no band name—just four mysterious symbols. Atlantic Records called it "professional suicide." Critics were hostile. The mixing was a disaster that nearly scrapped the entire project. Yet Led Zeppelin IV became one of the best-selling albums of all time, with 37 million copies sold worldwide. This deep dive reveals the untold story of how the album was made: recording in a freezing, supposedly haunted mansion with the Rolling Stones' mobile studio; the spontaneous jam that created "Rock and Roll"; Robert Plant writing "Stairway to Heaven" by fireplace; John Bonham's legendary drum sound captured in a stairwell; and the earthquake-plagued mixing sessions in LA that almost destroyed everything. Discover how this album defined hard rock, launched "Stairway to Heaven" as the most-played song in FM radio history, and became the foundation for hip-hop sampling through tracks like "When the Levee Breaks." Featuring insights from Jimmy Page, engineer Andy Johns, and the musicians who created one of rock's greatest masterpieces.
