That's the kind of rock and roll spirit we can get behind when an artist decides a facial infection isn't going to stop them from delivering the goods at one of the world's biggest festivals, you know they're serious about their craft. Halsey leaning into heavier arrangements and letting the crowd get properly stuck in with a mosh pit is exactly what Rock in Rio should look like, and it sounds like she gave it everything despite the circumstances. Whether or not those 100 witches came through with the goods, the real magic was clearly in the performance itself. Fair play to anyone willing to battle through that sort of thing just to give their audience a proper show.
