The Original Soundtrack to Relic Space, composed by Peter Gagliardi.

Tracks 3 to 19 are listenable versions of Adaptive tracks. For each track, the different variations have been laid out in a sequential order for a smooth listening experience; in-game, they transition depending on aspects of the player's state. The overall themes and moods of the tracks are tied to factions in the game, adding to the uniqueness of the different areas that the player can explore.
