Performances always dominate this well-run awards show, and this year’s program is scheduled to open with Taylor Swift, include Lady Gaga paying tribute to David Bowie and the remaining Eagles saluting their late bandmate Glenn Frey, and so, so much more. Oh, and the opening number from the Broadway smash Hamilton will be performed, live from the dark-on-Mondays theater where it’s the year’s biggest sold-out show. Also set to perform: Kendrick Lamar, Nicki Minaj, Justin Bieber, Ariana Grande, Carrie Underwood, the Weeknd, Selena Gomez and others.
