We’re past Memorial Day and it’s open season for summer parties. Where better to start than this bash thrown by Harper’s to mark 25 years in the biz. That quarter century has seen the gallery become a veritable institution of the Hamptons art scene. The diversity and quality of artists assembled in this celebratory show testify to Harper’s influence and spirit. Established heavy-hitters like Richard Prince and Christopher Wool share the walls with NYC’s younger darlings like Chloe Wise and Nicasio Fernandez. Even if you don’t know much about the artists assembled, the show is a great introduction to the Hamptons’ vibrant art scene.
