Do you know what a big group of musicians playing music is called? That's right, it's an orchestra! And a really famous orchestra is called the New York Philharmonic.
In 2008, the New York Philharmonic was invited to go on a trip to a country far away called North Korea. It was a big deal because North Korea doesn't usually let other countries come visit.
When the New York Philharmonic got to North Korea, they played a big concert with lots of people from North Korea watching. They played really beautiful music that made people feel happy and excited.
The people in North Korea were very surprised and happy that such famous musicians came to their country to play music. It was a special moment because it brought people from different places together, even though they didn't speak the same language or have the same culture.
The New York Philharmonic's visit to North Korea was also important because it showed that even if countries have different ideas or ways of doing things, important things like music can still bring them together.
