Metallica Rock the National Anthem at San Francisco Giants “Metallica Night” [VIDEO]

Metallica and the San Francisco Giants celebrated "Metallica Night" at Giants Stadium Friday night. And as always Met rocked everything they do!

That included opening the game with a dual guitar national anthem to rival any anthem ever done! As you watch the video, the guitars that James and Kirk are playing are also the ones they put up for auction. Pretty sweet. Rock America's ass with this one.
