I am going to have to step in and say a few things. I don't consider this to be as good as the Reunion arrangements like some are saying (What, are you out of your mind?) nor am I going to harp on it for being "chaotic" and such. I am really curious how many of these there will be. Given the scope of this thing (this suite only includes only the material of the 1st track on the ost) I'd say that there wouold at least have to be a dozen before the game is fully represented.
That said...
This is one remix that takes all the conventions of videogame musi and throws them out the windows. The lack of reiteratrion (vgm is composed so that it loops, while "real" music is not) and the surprising inclusion of non-thematic, stylistically coherent original material amidst undeveloped inklings of NU's themes (Remember, in a video game, every track is practically it's own theme, while a film score will only have a few themes scattered about in barious forms). The result is that this is without a doubt the most successful remix in acheiving it's own narration. Other remixes try to link images or story to the music but only this remix knows how to do that. Even most VGM orchestral albums don't do this (not that it's a bad thing) with the exception of FF6 grand finale (although the orchestrated version of Aeris' theme managed to be narrative, despite a complete lack of the aforementioned "original" melody that frees a piece of music out of it's videogame asthetics)
The end of Robon's piece, at least to me, clearly narrates the meeting of Coud and Aeris after the bombing mission (or at least the aftermath among the rubble prior to their meeting) in which the lifestream theme (heard among the opening ambience that is associated with Aeris' face) is hinted at in a subtle minor-key reprise beneath a shroud of mesmerizing original composition, which blends seamlessly with the source material. I have meditated on such a style of ff7 remix but hadn't the talent to pull it off. Russell says that the music after 4:15 seems to die, but I think that it is the music after 4:15 that makes the piece such a revolutionary remix. I hope that it continues in this direction, and as a narrative remix, continues through the various themes at this pace, telling a significant chunk of ff7's story (Which like I said before, would need at least a dozen parts) not like this will happen, but I can dream.
