Works by John Ashbery, Rudy Burckhardt, and Larry Rivers, three artists with long associations with the South Fork, are included in a group show at the Tibor de Nagy Gallery in Manhattan. Erica-Lynn Huberty will display an installation of her artwork and read from her Sag Harbor-based novella, “Watchwork: A Tale in Time,” tonight at 6 in the Malia Mills pop-up gallery space in East Hampton.
