It's very interesting to know that Metallica had a concert in Antarctica, the coldest, driest, and windiest continent. It's not really their usual concert, with only 100 audience, who are mostly scientist as there are no permanent human residents there. Well, they just want to make another history, though they were just the 2nd group to play there. With the extremely low temperature, a classic breath builder at wwbw maybe helped.
If North Pole has Santa, then South Pole has Metallica!!
