The Purple Room

"Rob is the kind of collaborator who all directors dream of finding. He is a true artist, and his command of his medium is not merely technical but deeply artistic. He absorbed the emotional and cultural nuances of my story and layered them deep into the sound design of Iké Boys. For Rob, craft and storytelling run hand in hand: sound is not just a mechanical task but an integral aspect of the cinematic experience. I’ll be going back to him for a long time to come."
