Mann is notorious for cobbling his film's music from different sources, sometimes even going so far as hiring a composer to score the full movie and then replacing half the original score with other pieces of unrelated electronic and techno music (just ask James Newton Howard about his experience on Collateral). For Last of the Mohicans, we have a similar oddity, two composers working on one film. Neither composer collaborating together, but each gentleman scoring different scenes. Jones was hired initially, but production delays and constant re-editing ended up running into another project he was working. Jones completed as much as he could and Randy Edelman was brought in to finish the project. Edelman provided some of the textural music, material that was lighter and used in the quieter scenes, with a few exceptions. Trevor Jones was brought in for his powerful themes and bombast. Mann managed to make it all work in the film, and as a listen on album it can be a bit uneven (especially with Edelman's uses of electronics). But still, that main theme by Jones is one of the most memorable of the 1990s.
So here is a sample of both men's work
First we have Edelman's music for a quiet scene early in the film, Cora.
And here is the dramatic Main Theme by Jones.
