Lost Tracks

Lost Tracks, the official Derail Valley soundtrack, is a music album containing pieces composed by Slobodan Stević for Derail Valley's trailers, main menu, or otherwise related. The album is a distinct, cohesive blend of post-rock, ambient electronic and orchestral sound.

The featured songs were going to be lost and forgotten, but were then collected and launched on May 15, 2018, as a way to further support Derail Valley development. This album went on to sell over 5000 copies.

In June 2026 the album was fully remastered, with all the existing tracks reimagined, done with higher quality and expanded, and new tracks added too, almost doubling the original album duration.
