US rock band Metallica has achieved a new Guinness World Records title after becoming the first musical act to play a concert on all seven of Earth's continents.
The band set the record after they entertained 120 scientists and competition winners in a transparent dome at Carlini Station in Antarctica on Sunday.
Metallica actually performed on all seven continents in a calendar year, following tour dates in North America, South America, Europe, Africa, Asia, and Australasia in 2013.
Sunday's hour-long show, appropriately dubbed "Freeze 'Em All", saw the rock band perform ten tracks including hits such as "One", "Enter Sandman" and "Nothing Else Matters".
Unlike regular Metallica gigs, the Antarctica concert was held without traditional amplification due to the icy continent's fragile environment.
Amplifiers were instead enclosed in isolation cabinets, with the sound transmitted to the audience via headphones, similar to "silent discos" sometimes found at music festivals.
The competition to win tickets for the concert was organized in conjunction with Coca-Cola Zero for Metallica fans in Argentina, Chile, Colombia, Costa Rica, and Mexico. The winners were invited on a week-long Antarctic cruise that stopped off at Carlini for the concert on 8 December.
Argentina's Carlini Station is located on King George Island in the South Shetland Islands, Antarctica, and is named after the Argentine scientist Alejandro Ricardo Carlini. The station was erected in 1982 and is only accessible by air and water via Base Marambio.
