LED ZEPPELIN IV

Although not progressive in the literal sense. This album does have alot of prog elements. Stairway To Heaven. Everything about it is so prog-esq. The spiritual themes, the passages and the tempo changes. The Battle Of Evermore. This is another prog song. You have the folkish manadlin and guitar and the vocals. Robert Plant is the caller and guest vocalist Sandy Denny is the answerer in this dramatic complex tune. Even the album cover has prog like themes. With the medieval symbols substituting as the titile. It's so dark and mysterious it would have had Jon Anderson Shudder!! So in conclusion, if you want a good prog-related album to get get this album. You won't be disappointed
