This article presents the composition process of three electroacoustic pieces belonging to the project Contra el racismo en Mexico (Against Racism in Mexico). The project aims to raise awareness about racism. Concerned with engagement, national identity, and the invisibility of racism in Mexico, I included fragments of interviews with Mexicans to share their views and call for a change. In the article, aspects such as compositional methodology, selection of sound materials, cultural aspects addressed in each piece, and engagement with society are discussed. Aesthetics and form are also examined, as they played a significant role when composing electroacoustic music for broad audiences. I argue that these pieces may have documentary qualities that depict racism in Mexico.
