SOAD frontman Serj Tankian, the Authentic Light orchestra and Swiss musician Veronika Stalder have unveiled a new soundtrack for the movie "The Promise".

The war drama centers on a love story involving a medical student (Oscar Isaac), a journalist (Christian Bale), and the Armenian woman (Charlotte Le Bon) who steals their hearts. All three find themselves grappling with the Ottomans’ decision to begin rounding up and persecuting Armenians during the first genocide of the 20th century.

Tankian has worked on the film and contributed to the modern interpretation of the national Armenian song "Sari Siroun Yar".
