Metallica performed the national anthem before Game 4 of the Stanley Cup Final, and it was as epic as one would have guessed. You can see the performance below courtesy of the NHL, and make sure to turn the volume all the way up.

The band is a big fan of Bay Area sports teams and the San Jose Sharks could use all the help they can get at the moment. The Penguins hold a 2-1 series lead heading into Game 4.
