I think Horner is very talented in using brass in unconventially subtle ways which can create very interesting and inspiring emotional effects. I think of his brass writing in a Beautiful Mind especially--in at least one of the darker tracks. I agree that his use of brass is effective as always in the Missing. I'd like to add that I like the last track of the Missing better than that of Legends of the Fall, too.
The whole soundtrack of the Missing seems to maintain a high level of
integrity--something not commonly found. There are so many soundtracks which seem to start out strong but then seem to fade in their integrity--A Perfect Storm, Black Beauty, A Beautiful Mind, Bicentennial Man, even Legends of the Fall, I think. But this score, as well as Horner's other most recent scores (Four Feathers, Radio, Beyond Borders) seem to be so painstakingly done, in avoidance of re-use of music from other scores, in originality, and in an overall sense of integrity and inspiration. What a wonderful breath of fresh air for Horner fans, especially... I really hope House of Sand and Fog follows this pattern!
In reference to the Missing, I haven't looked forward to the release of a new score and felt sincerely overwelmingly impressed with it as I have with this score since...well...Four Feathers! A. I. came before that, and then, well, there was a long stretch before then...
