Los Angeles City Hall was filled with music Tuesday as business and political leaders from China and the US enjoyed a special jazz performance by a group of talented musicians from Alexander Hamilton High School.

The event, put together by the China General Chamber of Commerce - Los Angeles and Sister Cities of Los Angeles, was a sendoff for the 20 students in the Hamilton High Jazz Ensemble.

They are headed next month to the 12th annual Sister Cities International Youth Music Festival in Chengdu, capital of Southwest China's Sichuan province, as LA explores a partnership with Chengdu as a sister city.

The July 23-to-Aug 4 trip is being sponsored by the Chengdu city government, CGCC-Los Angeles and Chinese companies in the US.
