Rules Of Engagement Soundtrack

Sometime in the mid 1980's, I heard an album called 'Vapor Drawings' by Mark Isham. One track in particular stayed with me all these years and I've gone back to listen to it repeatedly. The track is called 'On the Threshold of Liberty,' and I've wanted to use it in a film since I heard it, but never really had anything that I thought 'deserved' this sort of patriotic, wistful, ironic and beautiful melody reminiscent of the music of Aaron Copland. Mark Isham composed and arranged this piece as well as having played the trumpet solo, and over the years I've come to admire his work as a soloist as much as his compositions.
