Book excerpt: Could it be that playing marimba music is an act of resistance? Could it be a peace practice? Are musicians from the South Colombian Pacific coast region performing peace by playing their vernacular music? This book is concerned with these questions, as well as with the reflections about the concept of peace that they trigger. Through ethnographical research, the book examines peace as an active practice of self-assertion exercised in the daily life of the musicians from a traditionally alienated region in Colombia.
