The diverse cultures around Indus, with over 70 spoken languages, have deep roots going back centuries. Despite the richness of the various cultures flourishing along the mighty Indus river, their sounds have faded to the background in a world dominated by modern musical instruments. In this documentary, the filmmaker takes us on a journey spanning a thousand miles from the Karakoram Mountains to the southern coastline, capturing the little-known ethnic, linguistic, and musical diversity and humanism of the cultures of the Indus.
