Factory Noise & AG - Shanghai Alice of Meiji 17
I'd classify this as an orchestral remix, but not the standard all-out kind. Starts out simply, and builds up gradually. It's not an explosive arrangement, but the celtic folk elements sprinkled in give it a roaming sort of progression. It has some nice original interludes, too.
jesterdist - Nuclear Fusion
This one's more intense, but also utilizes a build up to get there. I'm still not satisfied with the loop transition, but that's to be expected. The instrumentation choices here are varied and unique, but complimentary. I'm not sure what category I'd put this in; it doesn't seem quite symphonic metal, but I suspect that was the intended genre.
