Tonight in Brooklyn, two of our favorite Rebelde artists will be performing at a FREE Concert at Prospect Park. Puerto Rico's Calle 13 and Chile's Ana Tijoux, two acts that we feel will continue to make waves as they begin to get more attention in the United States. For those who can't make it to Brooklyn tonight, NPR's AltLatino will be live streaming the concert. Now THAT is cool. We are also getting into Ritmo Machine, and that act will be there too.
