Cast In Bronze performed at Epcot during the Holiday seasons from 1998 to 2003. The instrument is called a Carillon and it consists of 35 bells weighing in at approx four tons. Below is a brief clip of a performance from Dec 8, 2000. That season the performances were held at the Christmas Tree. The video also includes a brief look at the Lights of Winter during the day and Monorail Purple gliding by.
Here are some stills from the video:
