Info from Licensor: "During a football game featuring the China Spring Cougars football team and the Addison Christian Academy Trojans, the China Spring Band's trombone and drum section decided to do an impromptu sideline performance of a routine in which trombonists do a synchronized act of swinging their trombones from left to right. The trombonist adjacent to them drops down and avoids getting hit with the trombone slide, incorporating some dancing, some spins, and some turns. The end result leaves the watcher impressed with the skill and timing of the trombone section."
