Led Zeppelin IV

"Led Zeppelin IV", officially untitled, was released on 8 November 1971. Produced by Jimmy Page, it was recorded between December 1970 and February 1971, mostly at Headley Grange in Hampshire. It features the band’s most iconic song, "Stairway to Heaven." After the mixed reception of Led Zeppelin III, the band opted for an untitled release with four personal symbols chosen by each member, replacing the album name and details on the cover. This record also featured guest musicians like Sandy Denny and Ian Stewart. It was a commercial and critical success, becoming the best-selling album for Led Zeppelin, with over 37 million copies sold worldwide.

The album's recording began in London and then moved to Headley Grange, using the Rolling Stones' mobile studio. The relaxed atmosphere allowed the band to experiment with different arrangements, resulting in diverse musical styles. Notable tracks include "Black Dog," "Rock and Roll," and the epic "Stairway to Heaven," which became a staple of the band's live shows. The album also includes "When the Levee Breaks," a blues cover with a distinctive drum sound.

The album was controversial at the time for its lack of title, but its success proved Page’s decision correct, making it one of the best-selling albums ever, and it continues to be highly regarded by critics. The album’s remaster in 2014 received widespread acclaim, cementing its status as a pivotal rock record.
