SURF’S UP: Sports have long inspired artists, and now a Manhattan exhibit is celebrating the culture of surfing. Called “Surf Culture — The Art History of Surf,” the exhibit will be on view at the Milk Gallery at 450 West 15th Street July 7-28, and covers the history of surfing from its origins in Peru and Polynesia through its current influence on pop culture. A block party on 14th Street featuring a performance by Sugar Ray was planned for Wednesday night. Presented by KIA motor company in conjunction with firms such as Op, Quiksilver and GQ magazine, the exhibit includes original work from artists such as Andy Warhol, Robert Irwin and Robert Longo and includes photographs, posters, films, surfboards and artifacts. For the duration of the exhibit, the Milk Studios will have surf demos and special events such as a screening of the surf movie “Riding Giants.” The exhibit is accompanied by a 240-page color book with essays by writers, surfers and anthropologists.
