Artists from across the African and South Asian diasporas grapple with colonial legacies through a reimagining of the lost city of Atlantis transplanted to the bottom of the Indian Ocean What if the book was a technology invented at sea? How would its language reflect the intonations of the sea? And how might we think of a Brown Atlantis at the bottom of the Indian Ocean without the blinkers of human navigation or instruments of measurement? Radio Brown Atlantis explores the entanglements between brown and Black people from the African diaspora and South Asia, displaced through enslavement and indenture, and connected through experiences of oceanic colonial routes. Using storytelling, music and poetry, this new anthology reimagines their stories and histories underwater, in an Atlantis at the bottom of the Indian Ocean, and the subaquatic ecologies and life forms surrounding them below. Originally a radio show broadcast on the Onassis Foundation’s Movement Radio station, Radio Brown Atlantis assembles contributions from 15 practitioners in music, visual art and literature to continue to imagine the cartographically unmappable.
