They're usually raging about the fires of hell and eternal damnation but now it seems metal overlords Metallica are set to go glacial with a gig in Antarctica.
The band appear to have booked a concert in the desolate southern continent as part of a competition run by a soft drinks company.
According to website Blabbermouth, which is known as the CNN of heavy metal news, the Coca-Cola Company in Colombia is giving fans in six Colombian cities a chance to go down south and see Metallica's "unique concert" at the bottom of the world.
The gig appears to be happening in December and earlier this year, drummer Lars Ulrich may have hinted at the show during a radio interview in California.
"There's a very interesting thing coming our way in December. If anybody [in management] even knew that I just said what I just said, they would hunt me down and silence me," he said. "But there is another frontier coming in December, which we're very excited about."
If the gig happens, Metallica will apparently be the first major band to play the wilderness. A band called Nunatak (not to be confused with Cork greats Nun Attax) claimed to have played the continent's first rock concert in 2007 to a "sell out" crowd of 17 people.
Enter snowman anyone?
