1975 Gatefold Pressing With Hype Sticker & Inner Sleeve. Led Zeppelin's untitled fourth album, also known as "Zoso," is a true slice of classic rock that is ingrained in time with "Stairway to Heaven" remaining one of the most beloved and influential rock ballads of all time. From the opening track "Black Dog," with its iconic riff and soaring vocals, to the epic closer "When the Levee Breaks," every song on the album is recognizable and a true FM hit. Some of the standouts would be the bluesy "The Battle of Evermore" features guest vocalist Sandy Denny and haunting mandolin and the funky "Misty Mountain Hop" and the psychedelic "Four Sticks." Led Zeppelin's "Untitled" album is a cornerstone of rock history and a testament to the band's unparalleled musical gifts. It's a must-listen for any fan of classic rock and an essential addition to any music collection.
