“SIREN,” a solo exhibition by Canadian-German-Jamaican artist nichola feldman-kiss, opens at Toronto’s Koffler Gallery. Extending her ongoing critique of colonialism, it presents eponymous Siren III (2022, image), underwater video with ambisonic recordings of vocal ululations to capture the migratory flows across the “geo-cultural corridor that is the north Atlantic,” and Siren IV (2021, image left), glacial CGI forms rendered on digital tapestries.
