I am looking for music similar to the soundtrack to the film Tigerland, specifically in the forest march just before the final confrontation scene between Wilson and Bozz (I can't find a clip of that specific scene but the same instrument and tune appears again as the "End Credits Theme," below, but merged into an orchestra). What genre, period, place and instrument is this, what musical tradition is this song based on, and where can I find more solos like it?
It sounds like a Vietnamese or Chinese string instrument. A remixed version can be heard in Nathan Larson's Tigerland theme (Youtube) from his Filmmusik collection. It does not appear to be listed by IMDB.
In the case that this song predates the soundtrack, and wasn't created just for the movie, I would like to locate and identify the specific track, its composer, and its performer.
