Robert Plant's Favourite Led Zeppelin Album

In 1974, Led Zeppelin returned to the country manor where they had recorded their 4th album, to record their first album for their own new record label. The sessions went so well that they decided to expand the album into a 4-sided double album, which they entitled Physical Graffiti. And it was released 50 years ago this week, February 24, 1975.

Randy Renaud marks its 50th anniversary by telling the story behind its creation, on the Chronicles of Rock.
