Nursalim Yadi Anugerah is a composer and multi-instrumentalist, whose works focus on sonic experimentation through cultural practice, knowledge, and cosmology of indigenous people and their activism related to entanglements of social-cultural and environmental issue in Kalimantan (Borneo). His work contains echoes of various styles – Kalimantan indigenous music and symbols, the Indonesian underground noise scene, ritualistic chants, and European avant-garde compositions – all unified under his political project: a critique of ecological devastation and the question of survival. Through his works, Nursalim also offers a rich critique by highlighting the junction between ecology, technology, and decolonization; a path amidst the impasse between theoretical academic discourse and the urgency of Kalimantan’s environmental catastrophe.
