MacLeod's description:

Genre: Soundtrack
Length: 1:15
Instruments: TBA

Beginning with heavy horns and percussion, the music is dark and intense. As cymbals crash the music gains in intensity quickly until an ethereal, somber flute plays a haunting, lilting melody full of tragedy and loss. The piece is very short, so it should be used for a scene that changes mood quickly as well. 040
