High Quality Content by WIKIPEDIA articles! The fourth album by the English rock band Led Zeppelin was released on 8 November 1971. No title is printed on the album, so it is usually referred to as Led Zeppelin IV, following the naming sequence used by the band`s first three studio albums. The album has alternatively been referred to as Four Symbols, The Fourth Album (those two titles each having been used in the Atlantic catalogue), Untitled, Runes, The Hermit, and ZoSo, the latter of which is derived from the symbol used by Jimmy Page for the album sleeve. Page often appeared onstage with the ZoSo symbol embroidered on his clothes.
