Racionais MCs - Brazilian Hip Hop

A crew from the favelas of Sau Paulo, who rap about police brutality, racism, poverty & crime. They also speak out for the black minority of Brazil, have worked with the Ministry of Education to develop ARAPensado e Educação (loosely translated as "The Rap Thinking and Education) program, and have done numerous benefit gigs to fund health clinics, youth sports programs, and samba schools. I'm still working my way through their exstensive back catalogue but wanted to give you a little taste.

Much respect to Siren for the tip off.
