Ya know, this is actually pretty damn good for a metal version of the imperial march (or, it's much lesser known title, "march of the conqourers"). Most metal songs that I've heard that tried to do the Imperial march seemed a bit... I dunno, too much thrash and not enough of actual MUSIC...
This seems to have a techno flavour, with a helluva lot of metal thrown in, which is actually NICE for a change. Also, I like how the "Duel of the fates" just slipped in there.
I think if darth vader, empourer palpatine, and darth maul, and count dooku ever had to start a garage heavy metal band, they would probably play something like this.
