Led Zeppelin’s fourth album was released in 1971 and is officially untitled, yet it goes by various names: Led Zeppelin IV, Four Symbols, Zoso. But whatever you call it, it’s arguably the greatest rock album ever made.
Jimmy Page - Zeppelin’s leader, guitarist, principal songwriter, producer and all-round genius - gave an interview to Classic Rock in 2014 in which he discussed the making of the biggest selling album of the band’s career.
