This document discusses a mix of popular songs from Mexico and the United States as well as Colombian themes that were initially copies of Aztec music. It specifically references Alma Records, a record label that has published ten volumes of these songs under the "Corridos prohibidos" series, with five being double albums. The promotion of this music did not start in Bogotá or other major Colombian cities, but rather in smaller cities like Florencia and Caquetá where local radio stations helped promote the songs from the new musical project.
