It is officially licensed by Mitsuda's company.
Masashi Hamauzu, known for his music on FF10, FF13 and FF7 Remake is arranging some pieces, but you also have Mariam Abounnasr who was involved in Oninaki and Another Eden, and Akio Noguchi, who is a pianist who performed for Xenoblade 2, Another Eden and Monster Hunter Iceborne. I believe all of it will be performed by Benyamin Nuss, who is the pianist of official Square concerts and he is an absurdly skilled one. Like one of the best I've heard live.
Kiyoshi Arai will be the artist for the album, who worked on FFXII, FFXIV and Xenoblade X.
STRETCH GOALS
We should at least have this battle medley!
Let me reiterate:
MASASHI HAMAUZU IS THE ARRANGER OF THE PIANO COLLECTION OF ONE OF THE BEST VIDEO GAME SOUNDTRACK IN THE WORLD. Please let make this happen, this is a one-in-a-lifetime opportunity
