Hello !
I put together a
google doc which lists all of Ultimate's new tracks and features :
- their composers (when known) and arrangers
- their performers (when known)
- a few other tidbits
The main goal of this initiative was to repertoriate all of the game's performers since a lot of music in Ultimate was recorded using live instruments.
I was not able to find some of the composers and performers info so any help is appreciated (of course with sources) !
