Originally called just "Epic" this song was all kinds of difficult when I wrote the initial riff maybe four years ago? It's still very hard mostly because it's just weird and awkward to play. I'll take that awkwardness for a cool sounding riff, though!
I did what I tried to do in maybe every song on Under Construction where I go from the core feeling of the song in a minor key and move it up into a major key. I manage to keep the energy, I think, so it's okay. I just love doing this and I don't know why!
