The acknowledged classic in their catalog, "Zoso" is also the album in which Robert Plant's mystical concerns took center stage on the Battle of Evermore; Stairway to Heaven, and the lighthearted Misty Mountain Hop. But Stairway aside, the album's real highlight is the downright scary When the Levee Breaks ; blues-rock never got better than this. From 1971.
