One of our most anticipated moments at the 2018 Oscars was Sufjan Stevens' performance of his Best Original Song nominated track from Call Me By Your Name, "Mystery of Love." He was joined on the Oscar stage by St. Vincent, Moses Sumney, Chris Thile, Casey Foubert, and his Planetarium collaborator James McAlister. Watch below.

Moses Sumney kept busy before taking the stage by tweeting from backstage, including a video of Chris Thile warming up. Read his tweets below.

"Mystery of Love" is up against Common & Diane Warren for “Stand Up For Something” from Marshall, Mary J. Blige for “River Bound” from Mudbound, Robert Lopez & Kristen Anderson-Lopez for “Remember Me” from Coco (sung by Miguel and Natalia Lafourcade), and Benj Pasek & Justin Paul for “This Is Me” from The Greatest Showman for Best Original Song. Who will win? Stay tuned to our full list of this year's winners to find out. UPDATE: “Remember Me” from Coco won the Oscar.
