I love this group. The Isiserettes are a non-profit drill and drum corps from Des Moines headed to D.C. in January to perform at Barack Obama’s inauguration. The official group is made up of kids ages 7 to 18, but I've seen some pretty tiny kids grooving out there (which is adorable).
This video is cool, but I have to say it doesn’t do them justice: they’re super impressive when you see them live. Here's a video of the drum line in action:
