Watch: Metallica performs Star-Spangled Banner before Game 4

The San Jose Sharks brought in the heavy artillery for Game 4 of the Stanley Cup Final.

Metal icons and California-bred Metallica performed their instrumental rendition of the Star-Spangled Banner immediately before puck drop between the Sharks and Pittsburgh Penguins Monday night.

Metallica's long been associated with the franchise, which blares Seek and Destroy through the SAP Center speakers when the team sprints onto the ice before games, and has previously held a promotional night for the band.

The guitars James Hetfield and Kirk Hammett used to perform the national anthem were signed, and are available for auction to benefit The Sharks Foundation.
