BODIES MOVE THROUGH LIGHT, RESPONDING TO AN INSTRUCTION THAT IS NEVER SPOKEN. MUSIC DIRECTS THE ROOM, PULLING PEOPLE CLOSER, SETTING THEIR PACE, AND SHAPING GESTURES BEFORE THEY CAN BE CONSIDERED. FACES APPEAR AND DISAPPEAR. MOVEMENTS OVERLAP. THE CAMERA DOES NOT DIRECT WHAT HAPPENS; IT CATCHES PEOPLE RESPONDING IN THEIR OWN WAY.
