It occurred to me that I never announced the release of the first soundtrack here. Whoops.

The A-Side soundtrack contains music from episodes 1 and 2 and can be found here on Bandcamp: http://vacantsky.bandcamp.com/album/vacant-sky-awakening-ost-a-side

The B-Side soundtrack has just been released! It contains music from episodes 3, 4, and 5 and can be found here: http://vacantsky.bandcamp.com/album/vacant-sky-awakening-ost-b-side Kickstarter backers who pledged for the complete soundtrack will be receiving a copy soon.
