Hello there,

I've recently made a half cover of the new FF trailer music. The first half is a complete cover, while the second half of the mix is a combination of my own chops with a little bit of what was going on in the trailer, combined with a little bit of hallow bastion-ish-ness (or what I thought Shimomura might do). This is simply because I couldn't hear clearly what was going on in the action scenes due to sfx and voice acting. You can find the mp3 of this in the description of the vid.

I am watching the battle gameplay video right now on IGN, and the music seems to be more audible. I may be off covering that one right now.

Thanks,

I'm adding in here the FF15 boss music. This is a cover of the music from the new gameplay footage. It's a lot more accurate. There is a free mp3 download in the description as usual:
