"Jazz is perhaps the most honest reflection of who we are as a nation. Because after all, has there ever been any greater improvisation than America itself?," said U.S. President Barack Obama, who with his wife Michelle, hosted the fifth annual International Jazz Day Concert at the White House.
The concert Friday will be broadcast across America Saturday — International Jazz Day — as an ABC television network special and streamed around the world by the United Nations and UNESCO.
"Jazz was born in the U.S. and traveled the world as a music of tolerance, freedom and human dignity. This is why UNESCO created International Jazz Day," said Irina Bokova, UNESCO director-general.
