We present “Open Code” in Puertas de Castilla a cultural center of contemporany art located in Murcia. Our artists in residence Jose Luis Fraga and Iván Lucas show us the research between colors and notes. The concert-performance have been a dialog with live music and generative graphics. The cave house of art N ground served for inspiration the exploration of armonic vibrations and lights and shadows. We have this presentation on Thursday at 21:00 in the audience of Puertas de Castilla. All of images used by Ivan come from rhino droppings, created by El Rhino Paper
