okay, These are some awesome bands. They will make you vacate your bowels in their awesomeness in remixing.
First is Hellion Sounds: They have some AWESOME SaGa remixes. They even fused two of the best Final Boss themes EVAH (IMO) seamlessly in an awesome arrangement/remix.
The related videos will take ya to the other awesome remixes....
There is also Sword of Justice, Phoenix Sword, SDH, Dark Phoenix, ERU, SSH, LIX, and others that I am too blinded by awesomeness to remember....
