Metallica was the first band to play a show on all seven continents. Of the entries on the list, this is one I find the hardest, even as a seasoned grump, to be annoyed by. Metallica has undeniably conquered the world musically, become a touchstone in heavy music and a band T-shirt colossus on the scale of Led Zeppelin. So, if they realized that all they had to do was source a couple amps in the Antarctic to get their names in the Guinness Book of World Records, it’s not like I could in good faith call it a technicality. It’s a relatively small achievement scale-wise, but one that rounds out a complete and total victory, like finally infecting Madagascar at the end of a game of Pandemic.
