If the basic thematic elements of this Bruce Willis star vehicle--American military unit gets cut off behind enemy lines in a guerilla-besieged African backwater--have parallels with Ridley Scott's fierce, unrelenting Black Hawk Down, composer Hans Zimmer (who scored both films) has conjured an entirely different musical soul for this adventure. Where his Black Hawk score turned on a gritty, often violent clash of musical cultures, his work here is richly introspective and tinged with a mature sense of melancholy. African rhythms and melodic elements bubble to the surface throughout, but in subtly powerful ways that often recall the best of Peter Gabriel's world music ventures. Zimmer has again impressively expanded his repertory company approach to scoring as well, with veteran collaborators Lisa Gerrard and Heitor Pereira joined here by Steve Jablonsky, Andreas Vollenweider and Lebo M. (who's written and performed the score's passages of African poetry). The result is a moody, evocative score whose quiet grace recalls the composer's masterful work for The Thin Red Line; another satisfying tribute to the power of musical understatement. --Jerry McCulley
