James Horner's score for "In Country" is a classic. It displays Horner's talent early on in his career, for memorable, delicate melodies and precise orchestrations. The music is melancholy without being extremely depressing or melodramatic. Also, this is indeed the precursor to Mr. Horner's 1994 score to "Legends of the Fall".
That being said, this music could easily fit into any introspective patriotic drama, such as Speilberg's "Lincoln". This film score is truly a classy, sincere and engaging listen.
