Really good song, reminded me of the Ace-Combat series,
Really wish it went into something more hardcore though, I mean it got epic, but when I think of the format for wordless songs, I think of the most slow/interestingly-grab-your-attentio n part, and then it goes into something awesome (sometimes dubstep) where the guitar for example would get louder, it would loose it's trance-like feeling, and continue to get more and more epic, on top of the intense-ness thats been building up, then make it more quiet, and sort of return to the first part where it's slower, and less upbeat, but still different. And from there make it more and more epic, awesome, fast-paced, hardcore, intense etc... until the end, where you just let that guitar chord go till it fades out
Thats what I expected, It was still completely awesome tho, so here is a 5.
