Welcome back to the second appointment of the week dedicated to Led Zeppelin.

Let's pick up where we left off. Led Zeppelin's fourth album, released in November 1971, is arguably the most significant in the band's history. Officially untitled, the album is commonly known as "Led Zeppelin IV" or also as the Runes Album or ZoSo. In this album, all the folk-Celtic influences already present in "Led Zeppelin III" blend with the characteristic hard rock elements of the band. The album cover features four symbols, each chosen by a band member. Jimmy Page chose a symbol resembling the inscription "ZoSo," Robert Plant a feather enclosed in a circle, John Paul Jones a circle with three points, and John Bonham three interlocking circles. These symbols, along with the music contained in the album, contributed to creating a mystical and enigmatic atmosphere around Led Zeppelin. Although it never reached the top of the Billboard 200, the album became the best-selling and most well-known of the band, surpassing 37 million units sold over four decades. Songs like "Black Dog" and "The Battle of Evermore" showcase the band's ability to blend hard rock and folk elements, while "Stairway to Heaven" has become one of the most famous songs in rock music history. In the following two albums, "Houses Of The Holy" (1973) and "Physical Graffiti" (1975), Led Zeppelin continued to explore and experiment with their music: these albums feature both lengthy tracks characterized by the use of synthesizers (think of "No Quarter"), oriental-flavored songs like "Kashmir," and others in the classic Led Zeppelin hard rock style.

Today's song is indeed in this style: "The Song Remains The Same"!
