Accidents, Disaster Performances & More! How The 2016 Grammys Turned Out To Be Its Most Bizarre Show Yet

Taylor Swift opened up the show with an "Out of the Woods" performance with Jack Antonoff.

The 26-year-old later accepted the award for Album of the Year — and took the opportunity to diss Kanye West. "There are going to be people along the way who will try to undercut your success or take credit for your accomplishments or your fame. But if you just focus on the work and you don’t let those people sidetrack you, someday when you get where you’re going, you’ll look around and you will know that it was you and the people who love you who put you there," she said in her speech.

John Legend, Demi Lovato and Luke Bryan performed a tribute to Lionel Richie.

Meghan Trainor helped them sing — and she later took home Best New Artist while giving a very emotional acceptance speech.

Adele was a show-stopper during her much-anticipated performance, but sound problems ruined the new ballad she wanted to sing after a microphone fell into the piano on stage, creating a "clanking" sound. After her disaster performance, she said, "Sh*t happens."

Kendrick Lamar put on a controversial performance.

Justin Bieber made a comeback — but between him slamming a guitar down on stage, his scruffy facial hair and his bizarre dance moves, it was difficult to pay attention to his performance.

The Weeknd made his red carpet debut with on-again off-again girlfriend Bella Hadid, and performed a medley of his only hits.

Sam Hunt and Carrie Underwood performed a country duet.

Lady Gaga performed a tribute to David Bowie, who happened to be one of her heroes. The pop-star-turned-actress even paid homage to him recently by getting a Bowie tattoo on her ribs.

Pitbull and Robin Thicke closed the show with the help of a special guest.

Sofia Vergara needed a taxi when she performed with Pitbull, but when the music stopped, she kept dancing.
