This chapter examines the polyphonic world of Mapostori—syncretic religious practitioners whose sonic rituals create complex atmospheric architectures in eco-political wildernesses. As a speculative outsider, I weave oral histories, fieldwork, and art practice to study how Mapostori Sound work shapes and is shaped by the idea of home, memory, and trauma. Their acoustic strategies—sonic territorial marking, spiritual Night marshaling, and sonic sacralization—form a complex Polisonitics that both resist and affirm colonial oppression reclaiming sonic and ecopolitical territory.
