Led Zeppelin IV

The untitled studio album by the English rock band Led Zeppelin, also known as Led Zeppelin IV, was released by Atlantic Records on November 8, 1971. It was recorded between December 1970 and February 1971, mostly at the country house Headley Grange, and was produced by guitarist Jimmy Page. The album is notable for including "Stairway to Heaven", which has been dubbed the band's "signature song".

The band was inspired by the relaxed atmosphere at Headley Grange, which allowed them to experiment with different arrangements of material and write songs in a variety of styles. After receiving lukewarm reviews for their previous album, Led Zeppelin III, the band decided that their fourth album would be untitled and represented instead by four symbols chosen by each band member, with no name or other details on the cover. The album was a commercial and critical success, and it remains Led Zeppelin's best-selling album, having sold over 37 million copies worldwide. It is one of the best-selling albums in the United States, and critics consistently rank it high on lists of the greatest albums of all time.
