caption: The image shows a group of men in military uniforms playing trombones in front of a crowd of people sitting in chairs. On the left side of the image there is a table with a microphone and other objects on it, and in the background there are curtains, a wall, a door, a sign board, and lights on the ceiling. The men are part of the U.S. Air Force Band, performing at the National Museum of the United States Air Force.
