I studied this subject briefly a while back, and here is what I found wrt long tracks. Some are obviously not prog but who knows what PA will add in the future. Seventh Sons, Zappa and The Doors are here so depending on the definition these could be argued as the having giving the first prog epic. Personally, I feel Procol Harum's "In Held T'was In I" is the first true prog epic, see the release date listed above. But you decide yourself:
