I wasn't at Orion yesterday. So Googled Metallica's Orion Fest to see what happened. I was pleasantly surprised to learn that Metallica came out to a fake band name entitled DeHann, and played Kill Em' All in its entirety. Rolling Stone has a great article on this.
When I saw the photo of James and Kirk wearing sunglasses, I knew something was slightly off. Metallica was a heavy metal band, not a fashion show :-). It's unusual for them to play in the midday, as they almost always headlines shows at night.
