Salsa icon Rubén Blades has joined forces with Latinx psych-rockers Making Movies to launch "No Te Calles", a song and a movement. No Te Calles is the first single from the upcoming album by Making Movies, a collaborative "mixtape" the group will release in May. The powerful voice of Blades soars over the explosive guitars and the rumbero percussion of Making Movies, produced by the legendary Steve Berlin, member of Los Lobos. The chorus urges 'Sal a la calle / Y no te calles' which translates to 'Go out on the street and don't be silenced,' a message that births a movement on NoTeCalles.World, a web portal where artists and fans can record their voices onto a chorus that will be added to the song. All the contributions will be stitched together in a musical and technological experiment called 'Making Movies and Rubén Blades ft. The World,' quite possibly the largest and most extensive musical collaboration in history.
