César López, Colombia
César López is a Colombian musician and peace activist. For the past several years, López has been part of a group called the Battalion of Immediate Artistic Reaction, which consists of various other musicians and activists who seek an alternative to the ever-present violence that plagues Colombia, and specifically the capital, Bogota. When the group receives news of another violent attack in the city, they meet and head out to the streets of Bogota to play soothing music for victims.

López' most extraordinary achievement is a project where he has guns, including several AK-47s, decommissioned and turned into guitars, the Escopetarra. So far, only a few dozen of these guitars have been produced, but upon completion, López gives the guitars to high-profile musicians across the world, such as Bob Geldof. In Soldiers of Peace we also see him working with a group of boys who through their own tragic stories and hip hop music unflinchingly tell us of the realities of violence and the devastating effects it will continue to have on the future generations in Columbia if nothing is done about it now.
