The old Americana Dawn soundtrack used in the RPGMaker/C++ engine era has now been recently released on Soundcloud, with commentary and the cover art for each of the songs from screenshots spanning between the two eras (including songs that didn't make it between the transition). However, what's more interesting is the backstory regarding the release of these tracks.
The soundtrack descriptions might reveal spoilers and important plot points about the game, though it may not be relevant anymore considering the fact that AD may be headed into a new direction. Notably, this includes Cadence; despite her appearing in various pieces of concept art in 2013, her character bio included in the soundtrack was never publicly released.
It is worth noting that as the result of this music no longer being used in the game, none of the original assets as seen in the original (2012) Kickstarter trailer will be part of the final product.
None of the official game pages have made mention of this album release.
