The objective of this work, part of a research project conducted at the Universidad Nacional Arturo Jauretche during 2018-2020, is to foster reflection on the origin of the practice of rap music in Argentina, mainly in Buenos Aires City and its surrounding suburban area, pinpointing the emergence of composers and singers on the local rap scene. The lack of archive material and scarcity of documentary sources protecting such records – which might have served as input for this research – prompted us to tap a diversity of untraditional sources. Mainly, we had to resort to oral history as the primary method of data and personal files collection. In this sense, this works recovers testimonies from Argentina’s first rappers, DJs and local party organizers, thanks to whom we were able to identify three sources of origin.
