I've seen drumline, but I wasn't too thrilled with it.
It reminded me of the Cheerleader themed movies that
seem to have popped up lately.
As for these guys, I'm not sure how I stumbled on them
(Saturday nites can be sooo confusing sometimes!).
None-the-less, did some search for them now, and here's
some info:
They are the Top Secret Drum Corps from Switzerland.
This appears to be their official site:
