San Keller might be late for Labor Day, but he’s never late for work. The artist’s first Latin American retrospective will showcase a body of work full of wit, humor, and a keen sense for letting art take over everyday situations. Over the course of four days in San José, the artist will revive performances inspired by specific workplaces, joining forces with a hairdresser, a physical therapist, a bar owner, a merchant, and even local cops.
