Mine is Seventh Son
They should have stuck to normal-length songs.
Don't know if it's "epic", but "The Trooper" is badass....
For the Greater Good of God
Rime of the Ancient Mariner is probably my favorite epic Maiden song. They have a lot of them though. I learned most of Hallowed Be Thy Name and Phantom of the Opera (both about 7mins long) in the past few weeks. Just polishing up on the solos now.
I think mine would have to be Seventh Son as well.
Sign Of The Cross, every time.
All early epics are very good, except Seventh Son and Alexander the great
when the wild wind blows, rime of the ancient mariner and Empire of the clouds. Though all of them are amazing (mostly).
Either Paschendale, or Isle of Avalon; tough call though.
Rime of the Ancient Mariner hands down.
