Entropy Zero 2 OST

Infiltrate

Dark Stalker

Expansive ethnic woodwinds, sweeping strings and exotic male and female vocalizations combine with driving, warring percussion in these action-packed, Mid-East orchestral trailer cues, summoning a strong sense of adventure and place with regional oud, lute, zurna, santoor, gadulka, and laouto.
