[Text nur in englischer Sprache verfügbar] Antimatter is a performance inspired by antiparticle notions. These concepts will be applied to the collision between sound frequencies producing their annihilation. Each action does not add, subtract. The images follow this same subtraction mechanics. The visualization is generated from the sound data using the GAmuza software. The sounds are produced in real time using electric bass, electric guitar and computer. Research project carried out at the Polytechnic University of Valencia and funded by the Generalitat Valenciana with reference GV / 2017/028
