Video - Marching Bands

My grandson, Evan, was in his high school marching band and we went to a few of his concerts.  They were pretty impressive.  Here is an amazing display of the art however, sent to me by my friend Kevin.  It's the Ohio State University Marching Band. It takes 8:50 minutes. http://www.youtube.com/watch?v=DNe0ZUD19EE&feature=youtu.be
