`Ecbatan` is a sound art project for four speakers, plywood, and a transducer. In order to streamline the presentation process for the festival, the work is only sent as a four-channel installation. `Ecbatan` is basically a dialogue between two places, two times, and two different approaches. To shape the core of his work, the artist has used sounds he had recorded in Tehran and Belfast with a ten years gap. The material used in this work is a combination of field recording, studio recording, and computer coding. Within 10 minutes and 56 seconds, the work moves from an open angle with a full spectrum towards more inward spaces, so that in the final section, it is as if the listener is inside the speaker.
