On November 13, 1971, one of the most iconic rock bands of all time, Led Zeppelin, released their fourth studio album, commonly known as "Led Zeppelin IV." This album would go on to become a seminal work in the history of rock music and cement the band's legendary status.

The album was recorded at Headley Grange, a former poorhouse in Hampshire, England, using the Rolling Stones Mobile Studio. The band decided not to give the album an official title or even print their name on the cover, instead opting for four symbols representing each band member.

"Led Zeppelin IV" features some of the band's most well-known and influential songs, including "Black Dog," "Rock and Roll," and perhaps their most famous track, "Stairway to Heaven." The latter, an epic 8-minute composition, has become one of the most played and celebrated rock songs of all time, known for its intricate guitar work, poetic lyrics, and dramatic buildup.

The album showcases Led Zeppelin's signature blend of hard rock, folk, and blues influences, as well as their exceptional musicianship and songwriting abilities. It has sold over 37 million copies worldwide, making it one of the best-selling albums of all time.

"Led Zeppelin IV" has left an indelible mark on the world of rock music, influencing countless artists and bands in the decades that followed. Its impact continues to be felt today, more than 50 years after its initial release, cementing its place as a true masterpiece in music history.
