UPDATE: Metallica have confirmed they're playing Antarctica! The Coca-Cola Zero sponsored stunt "Journey to the Bottom of the Earth" will give fans in Argentina, Chile, Colombia, Costa Rica and Mexico the chance to be part of their sub-zero concert on December 8 in Carlini, Antarctica. As for the rest of us, it will be "filmed to share with everyone at a later date."
According to a notice on Coca-colazero.com.co, the reigning metal kings will rock earth's southern-most continent between December 2-15. Much like James Hetfield's heart, Antarctica is 98% ice. Unlike Hetfield's ticker, it's also twice the size of Australia.
Further evidence this is actually happening: Earlier this year, Lars Ulrich promised the following: "There's another frontier heading in Metallica's direction in December." And Coca-Cola sponsors yearly trips to Antarctica, so we're thinking this seems very likely.
For the record, Metallica won't be the first band to play on Antarctica. Back in 2007, Live Earth had a band of scientist-musicians called Nunatak play Antarctica as part of a stunt that involved simultaneous shows in all seven continents. But Metallica will be the first recognizable artist to hit the icy land mass, much to the chagrin of electro-pop maestro Penguin Prison.
