Do you know the answer to this?   Who is the only band to have played live concerts in all seven continents in one year?

This band performed on this date in 2013, in a dome near an Argentine Antarctic military base, sponsored by Coca-Cola Zero. In fact, there were no amplifiers, the attendees were given headsets and the sound was transmitted that way.  Less sound equipment had to be transported and exposed to the weather conditions.  Pretty unique, eh?

Who was this band...?

The answer is Metallica.   Check the 2015 Guinness Book of World Records.
