Daniel Heidkamp’s solo exhibition includes mostly paintings made en plein air in Central Park. While so many of the Brooklyn-based artist’s peers are content to “dialogue” with Minimal and Conceptual art, Heidkamp’s conversation reaches farther back, to the Fauves and Impressionists, or even the Barbizon school. With slyly sophisticated compositions and a nuanced palette, Heidkamp makes a strong case that observational painting cannot simply be ceded to the Sunday artist. A group of canvases depict the exterior of the Metropolitan Museum’s Lila Acheson Wallace Wing, an angular structure of mirrored glass. Looming behind a grove of lush pink cherry blossoms, the museum appears as monument to culture that compliments the park’s cultivated ecology.
