A lonely acoustic guitar adds some mournful music to this track, which is otherwise filled solely with gunfire and the occasional whinnying of a horse. If you use this during an RPG session (Deadlands or whatever), I would suggest keeping the volume somewhat low so that you don't have difficulty hearing one another at the table. At any volume, it's a great way to add to the sense of immersion, whether the PCs are involved in the gunfight or are engaged in other activities while the gunfight rages outside in the street.
