When I first heard this song, I didn't think it could be done by someone as young as this guy. It sounded something closer to a John Williams/ James Horner piece, which brought shivers down my spine at just how awesome it is. The way the vocals in the piece are presented are surprisingly real sounding- it almost made me think that this guy got a group of people to sing while he recorded them. And the seamless transitions from DMC to MGS2 are flawless- it sounded like one beautiful song, ripped and put on this site from a musical soundtrack.
I've yet to find anyone even half as good as this guy. And that, people, is saying something.
