Umphrey's McGee is a critically-acclaimed ("They're the next Phish!" For whatever that's worth.) American prog-rock band, here playing a short instrumental piece at a concert in upstate NY. They decided to strap a video camera onto drummer Kris Myers to find out exactly what it is he does back there.
As it turns out, quite a bit. Hitting the skins, obviously, but also adjusting mic stands; repairing his kit; flipping drumsticks -- and, for all I know, brushing his teeth and making sandwiches for the backstage party. (I'll need some more camera angles to be sure.) It certainly adds credence to my theory that all drummers are grown-up ADD kids.
