There’s a lot to understand in Childish Gambino’s ‘This Is America’. With ‘3005’, ‘Sober’ and ‘Redbone’, Donald Glover showed that he could deliver some instant classics, but the wildfire that is this is song was hard to see coming. In the first 60 mins after the Hiro Murai-directed video was released, it had racked up over 1 million hits on YouTube, 10 million in 24 hours and 50 million in the 3 days since. It’s well delivered, thoughtful and dark. Step aside, Childish Gambino is in the house.
