music in Carandiru

I'd like to know if there's someone reading this msgboard, who could tell me the artist/title of the hip-hop track (in portuguese) that appears in Carandiru somewhere at the middle if i'm not mistaken? I think this was the only hiphop track in the whole movie.

Are there any good Brazilian hip-hop artists similar to the Ugly Ducklings, Delinquent Habits, Arrested Develelopment, Diggable Planets, People Under The Stairs, KRS-One, Mos Def, Cypress Hill?

Thank you very much in advance!
