The soundtrack for Itzpapalotl (Obsidian Butterfly) can be enjoyed with the comic MAPS.

The soundtrack is an hour long minimalist ambient piece that shifts smoothly from chamber to chamber. It was composed using many layers of sound fragments and loops taken from political marches, movies, tv shows, childhood recordings and the political left wing protest songs of the early 80s.

The fragments are interwoven with each other and refer to each other in unpredictable ways. They gyrate around a common sublime object, a non reducible “thing” that is touched by all of them but cannot be expressed by any one of them in full, a certain something that includes (but is not limited to) a boy's eye view of the civil war of El Savador; the most cruel, the most vicious, the most heroic, the most beautiful, the most mundane, the most intangible, all in one single place, all at one single time.
