“Catalyst,” a hybrid exhibition featuring artists including Carla Gannis, Auriea Harvey, Caroline Sinders, and Sammie Veeler simultaneously opens at Los Angeles’ Honor Fraser and online at EPOCH. The final instalment in a trio of shows curated by EPOCH’s Peter Wu+ set in CGI models of LACMA and its environs, this edition is set in architect Peter Zumthor’s forthcoming building for the county museum—in post-apocalyptic LA (image). IRL visitors plug-in to the dystopian vision via VR headset.
