As part of T’s 2023 Art issue, we compiled a list of 15 New York City gallery shows that changed art history. We attempted to be as objective as possible but were also aware that there are countless other exhibitions that, whatever their contributions to the culture at large, live on in individual consciousnesses. And so we asked a group of artists, curators and writers, as well as one collector, about the shows held in a New York City gallery or alternative art space that changed their lives. Here, they each speak about an exhibition (or two) that transformed how they thought about art — or simply blew them away.
