Kudos to my wife for finding this video, apparently passed on to her by another music teacher friend, who found it from another friend, etc. etc.  In any case the video is quite impressive.  At first I was like, oh, thanks honey, an indoor marching band video (like I haven't seen a lot of those in my time..) plus the hats and knee length pants made me think it was just an old drum corps video from ten or fifteen years ago.  Then I actually watched it and about halfway through it hooked me.  Nothing like a little LED sound activated bling on Pearl marching snares to make me take a second look.  

In case you are wondering it is a Scottish drum corps called Top Secret.
