It was 50 years ago today Led Zeppelin released its legendary untitled fourth album, generally known to the public as “Led Zeppelin IV.” The album, which has never left the FM airwaves, still plays like a greatest hits collection, featuring such instant era-defining classic rock staples as “Black Dog,” “Rock And Roll,” “The Battle Of Evermore,” “Stairway To Heaven,” “Misty Mountain Hop,” “Four Sticks,” “Going To California,” and “When The Levee Breaks.”
Upon release, “Led Zeppelin IV” spent four weeks at Number Two — unable to displace either Sly & The Family Stone's There's A Riot Goin' On and then, Carole King's Music. It was the last studio album Zeppelin released while still a working band that failed to top the charts.
All told, “Led Zeppelin IV” spent 14 weeks on the Billboard 200 charts, selling 32 million copies worldwide — including 23 million in the U.S. alone. The album is currently the fifth best-selling album of all time in the States.
