BUENOS AIRES: US heavy metal band Metallica can now say it has performed on every continent after giving a rare concert in Antarctica to about 100 spectators wearing headphones. Sunday evening’s unusual concert, near a glacier and inside a transparent dome on Argentina’s Carlini base, took place in daylight because of the continent’s far-southern location, Argentine media said. Sporting a fur hat and sunglasses, lead singer James Hetfield told the select crowd: “Are you ready to make history? So are we!” The dome protected the band and the small crowd from the ferocious icy winds sweeping Antarctica, with the audience - scientists and a few other guests - wearing headphones to protect the environment. The concert was wired for sound with a generator and solar panels, but without amplifiers or speakers, and was broadcast live on streaming and later put on YouTube.–AFP
