Simply Excellent.
A superb piece of work. At first I saw a caravan(like in the title) meandering across a desert. Then the music built up and exploded as a group of bandits attacked. A battle ensued, music perfectly matching every blow dealt, and I saw someone fleeing the battle. It must have been someone of importance as their clothes were of much greater quality than the rest of the caravan. The track calmed down as the person trudged on through the desert, not knowing where or what direction they were headed. End. (hey, you said it can provide visuals, I'm telling what I saw)
