Most important things first:
WATCH THE VIDEO for the fully orchestrated version!
The audio upload contains a few more solo organ fragments, which are part of the dubbed version in the video. (Remember, unfortunately I may not upload the fully orchestrated piece due to ToS restrictions.)
The full version is available on MEGA cloud storage and can be downloaded as 7.1 FLAC and 320kbps stereo MP3 files. The following download link is automatically unlocked as soon as the premiere starts at 06/06/20 4:15pm EST / 8:15pm GMT / 10:15pm CEST.

What you can experience in this compilation is an extra "organ track", which I played and recorded in parallel while the OST was playing and which was dubbed onto the OST later in a post-processing stage. This felt exactly like being part of the OST orchestra, where I would have the duty of contributing to the game music. Nonetheless, this had a bit of "adding even more gravity" to a score that was already perfect -- and to make things even more difficult, I played along solely by ear, i.e. without any sheets. The tricky part for me, albeit I had listened to the OST many times before, was to instantaneously react to chord changes and a melody which I roughly had memorized, but not exactly note by note.
Adapting the organ registration (i.e. selecting appropriate stops) to find a volume/dynamics level that was compatible with the orchestral part was another challenge that came on top of "just playing matching notes and/or an additional voice". While the intention was to make the organ present of course, it was always thought as an enrichment and strong foundation backbone, which should never speak over the orchestra too aggressively to achieve the impression that the organ would feel "natural", as if it would always have had its place and role in the original score right from the beginning.
Have fun -- hope to see you at the premiere!
