My pleasure @aerozol
In the Steam release, additional tracks with respect to the Bandcamp streaming version are tracks 71 to 90. The 91st Steam track corresponds to the 71th Bandcamp streaming track.
Discogs lists 90 tracks and says
Distributed via Bandcamp.
Tracks 71-89 are bonus tracks, only available through download.
The 91st track is then “God's Call.” It is a 37" song with the same theme than “Big Boy's Call,” “Child's Call,” “Father's Call,” … but with trumpet only.
