Metallica played their first ever show in Beijing earlier this week, and did not disappoint. Not only did the set list include all of the old and new classics, but they had a surprise in store for fans during the encore. Just as they did at the Grammys back in 2014, Metallica brought pianist Lang Lang on stage to perform ‘One’, and the audience in LeSports Center went nuts. Check out official video of the special performance below!
