The mp3. (file size: approx. 4.7mb)
Ok, for those of you who remember the FF6 boss battle mp3 remix he (Braxus, of VGmusic.com fame) did that I posted the link to, I've got some fresh meat for you to sink your ears into.
He recently got a new Yamaha MU2000 XG hardware external synth, and of course, with him having what seems to be a fetish for the FF6 boss battle theme (he's done like 5 or 6 different remixes), he's done another one.
It sounds totally different than the last one, but it is still hardcore rock style.
For those of you in disbelief, YES, that is a synthesizer. No actual guitar recording or soundfonts involved.
-edit-
Changed the first line to something that, needless to say, could be an appropriate description.
