Watch: AMON AMARTH Plays Surprise Set At Germany's WACKEN OPEN AIR Festival

Swedish melodic death metallers AMON AMARTH played a surprise set at this year's Wacken Open Air festival on Thursday, August 4 in Wacken, Germany.

After the performance, the band took to its social media to share a short video of the concert, along with the following message: "Heathens! Thank you for joining us today on the glorious battle ground of @Wacken
for a surprise set. Until next time!"

Earlier this week, AMON AMARTH teased the show as an appearance from a band called GUARDIANS OF ASGAARD, which, they said, would make "a brief appearance at Wacken on Thursday to play some of your favorite AMON AMARTH hits."

Wacken Open Air takes place annually in the village of Wacken, which has a population of just about 2,000.

Up to 85,000 people attend the event, which is 32 years old.

200 bands are scheduled to perform at this year's Wacken Open Air, including headliners SLIPKNOT, POWERWOLF and JUDAS PRIEST.

Wacken Open Air was forced to take a break for two years due to coronavirus restrictions.

AMON AMARTH has just released its twelfth studio album, "The Great Heathen Army", via Metal Blade Records. The LP was recorded with acclaimed British producer Andy Sneap, who previously worked with the band on 2013's "Deceiver Of The Gods" and 2016's "Jomsviking" albums.

This past February, AMON AMARTH released a standalone single, "Put Your Back Into The Oar", an ode to the epic Viking row. The track was recorded and mixed in January 2021 at Fascination Street Studios in Sweden with producer Jens Bogren and was made available via the band's own label Victorious Music.

The "Put Your Back Into The Oar" video was shot in England over three days in October 2021. The atmospheric, cinematic clip was produced by Twin V and directed by Ryan MackFall at Crashburn Media.

AMON AMARTH will team up with MACHINE HEAD for the "Vikings And Lionhearts" co-headlining European arena tour in September and October. A North American tour with CARCASS, OBITUARY and CATTLE DECAPITATION will follow in November and December.

AMON AMARTH stands tall and unassailable: 30 years into a career that has seen them evolve from humble origins in the dark, dank rehearsal rooms of their native Tumba to their current status as explosive festival headliners and one of the metal world's most widely adored bands.

Formed in 1992, AMON AMARTH became modern metal greats the hard way. Ruthlessly dedicated to creating new music and taking it out on the road, the Swedes steadily built a formidable reputation as a ferocious live band and, as the years passed, were increasingly recognized for their recorded achievements too. Since the dawn of the millennium, AMON AMARTH has been unstoppable.

Breakthrough releases like 2006's "With Oden On Our Side" and its now-legendary follow-up, 2008's "Twilight Of The Thunder God" further cemented their popularity throughout the metal world, while the band's stage show evolved with each successive tour, transforming into one of modern metal's truly great spectacles. "Berserker" brought with it an epic, history-making trek across North America with fellow Swedes ARCH ENEMY, AT THE GATES and GRAND MAGUS and saw multiple sell-outs.
