Led Zeppelin Four Symbols by Alberich Potter

The untitled 4th album by Led Zeppelin, variously known subsequently as Led Zeppelin IV, Four Symbols, The Fourth Album, ZoSo, The Hermit, Untitled and Runes. It is one of the biggest-selling and critically-acclaimed albums of all time, represents the band at the pinnacle of their career and is still, to my mind, the greatest rock album ever by the greatest rock band of all time.
