Rodrigo D: No Futuro (Víctor Gaviria, 1990)

Rodrigo D: No Futuro features Rodrigo and his friends in Medellin, Columbia. Living in the slums, Rodrigo and his friends steal, carjack, start fights, and at one point, shoot someone. Rodrigo's heart is with punk music, and he wants to start his own punk band. In one scene, Rodrigo and his friends are on a rooftop, practicing punk music. 

The film's gritty and neorealistism is what makes this film so great. Gaviria creates Rodrigo's character as angry and destructive, which falls in line to the music he listens to. Medellin is notorious for its crime, and I thought it was really interesting that Gaviria cast the movie with local teenagers, only so that they could live their life to some standards before the city swallowed them up.
