Just like Charyoshi, this gave me goosebumps.
This was awesome, just totally awesome.
It magnificently catches the grandeur of the game and the highly menacing characters of Lavos. When the slayers kicked in at 3:08 I was like '...ohhhh YEAH!'
The transitions between the songs could indeed be better, but this flaw is so minor compared to the rest of the song that it's not worth it taking points.
Well done! Keep this up and you'll be famous soon!
