For many years now, the American government has used jazz ensembles as cultural ambassadors, sending them out on international tours (Fun fact: The CIA used Duke Ellington's tour of Iraq in 1963 to help stage a coup that would pave the way for Saddam Hussein to become the country's leader).

Luckily for us, The Jazz Ambassadors, the Army's touring big band, performs both internationally and domestically. The talented group will play a mix of swing, bebop and popular tunes Saturday night at the Chemical Abstracts Service lawn to kick off this year's Picnic with the Pops series.
