Like all award shows, the Grammys are needlessly long, bloated, and self-congratulatory.

And every year, there are a few performances at the Grammys that are worth sticking around all night for.
That’s why we rounded up the best performances of the night, so you can happily live your life without seeing any award show banter whatsoever and feel confident that you didn’t miss anything.>
