Asked about his use of sound, Apichatpong has this to say: “I want it to resonate in the heart.” Does it resonate in the world? “What's that sound?” Apichatpong's films suggest many answers to this recurring question, or no answers at all, only openings. Loud bang in sleep, subliminal roar, deep groaning voices of howler monkeys; all inchoate, the invisible entity that stalks us through life. Sound is here on earth with us, calling to another place, beyond physical life.
