This is the awards show where the performances are the best part of the show – which you can say of the Grammys and the Tonys, but not for the Emmys or Oscars. Tonight’s scheduled performers include Adele, Bruno Mars, Chance the Rapper, Katy Perry, and some of Grammy producer Ken Ehrlich’s famous musical teamings. This year, the pairings include Lady Gaga and Metallica, as well as Maren Morris and Alicia Keys, and, somehow, The Weeknd and Daft Punk. The host is James Corden, who ought to be perfect for this.
