***Proibidão is the name given to a certain kind of electronic funk music produced in Brazilian favelas, especially in Rio de Janeiro where it started to appear in the beginning of the '90s as a parallel phenomenon to the growth of drug gangs along the city's more than 600 slums. A raw mix of live funk vocals and Miami bass structures, these anonymous funk tracks are spread illegally by DJs and gang-sponsored parties. Proibidão is a raw musical genre that captures the dark side of Brazilian favelas. The explicit lyrics of apology to drug gangs and the violent content makes them illegal to broadcast through radio or as live public events. Proibidão can only be heard in the bailes or dances that the gangs organize and that run every day of the week in different locations in the slums around Rio. All audio imperfections are left as they were when collected, as these tracks are the only remaining documents of this music. Recorded and assembled by filmmaker Carlos Casas, courtesy of some anonymous MCs and DJs in different bailes along the favelas of Zona Sul, Rio de Janeiro during March-April 2003.
