Watch Metallica’s James Hetfield and Kirk Hammett play the National Anthem at SF Giants game

When classic rock fans look back at bands that emerged out of the San Francisco music scene, they typically think of the city’s psychedelic Haight-Ashbury era with the artists like Grateful Dead or Jefferson Airplane. Metallica however, may be the most commercially successful band to ever come from the Bay area. So it was only appropriate that the two guitarists from the iconic metal band were welcomed onto the field to perform America’s National Anthem prior to the San Francisco Giants’ baseball game on Monday night.

As seen in the video above, Kirk Hammett and James Hetfield, both decked out in Giants apparel and playing with team-branded guitars and amps, turned their distortion all the way up to deliver a rocking performance of the “Star Spangled Banner.” This isn’t the first time Metallica have found their way onto the Giants’ field before a game. Monday was actually the team's fifth annual “Metallica Night,” where fans could even buy limited edition Metallica/Giants t-shirts.

The band will headline San Francisco’s Outside Lands Music Festival this coming weekend, which will be their last performance in the U.S. before they head over to Europe starting on Sept. 4. The European run will keep the band very busy until well into 2018 as part of their Hardwired World Tour, in promotion of their latest hugely successful album under the same name.

Tickets for select shows on their 2017-18 European run are on sale now, and can be purchased by clicking here.
