As the New York Philharmonic played the opening notes of “Arirang,” a beloved Korean folk song, a murmur rippled through the audience. Many of the staid spectators at this historic concert on Tuesday night perched forward in their seats. “This is difficult to describe,” said one journalist’s government-assigned minder, who was sitting in the audience. “My heart is booming. It’s too exciting.” The audience applauded for more than five minutes, and orchestra members, some of them crying, waved. It was the first time a major American cultural organization had appeared here, and the largest contingent of United States citizens since the Korean War. The trip has been suffused with political importance since North Korea’s invitation came to light last year. It was seen as an opening for warmer relations with the United States, which North Korea has long reviled. (Via NYT )
