Recently I read about this non-profit and its website in the New Yorker magazine (May 4, 2020). Since the pandemic, the magazine's listings of art events have shifted to on-line resources for movies, dance, music and visual art.
Art21.org is a treasure trove of information about art in the 21st century. Among the more than 200 artists profiled on the site are Marina Abramović, Ai Weiwei, David Altmejd, El Anatsui, Louise Bourgeois, Theaster Gates, William Kentridge, Maya Lin and Judith Scott.
