Framed as a full-on spiritual encounter, Seoul Mediacity Biennale’s 13th edition explores mystical traditions. The flagship exhibition “Séance: Technology of the Spirit” at Seoul Museum of Art (SeMA) features artists past and present who ”bridge material and immaterial worlds” including Joseph Beuys, Johanna Hedva, Haroon Mirza, and Angela Su. Conceived as a séance, the show moves beyond the ”neoliberal conception of biennial exhibitions,” according to the artistic directors (all from e-flux).”
