Music’s biggest night just keeps getting bigger every day as we get closer to Sunday. Even more performers were added to the already packed line-up, which makes you wonder if the Recording Academy plans to actually give out any awards during the broadcast.

CBS and the Grammys announced today that “Chandelier” singer Sia and Beck, who will perform with Coldplay’s Chris Martin, were both added. Mary J. Blige will take the stage, as will Latin pop star Juanes. Best New Artist nominee Brandy Clark will also get to give her music a wider audience. Acclaimed pianist Lang Lang will also play.

The All-Star Grammy Moment will be headlined by the legendary Herbie Hancock, who will perform with Questlove, John Mayer, Ed Sheeran and the recently reunited ELO.

On Tuesday, Kanye West was added to the line-up twice. He will perform solo and then take the stage with Paul McCartney and Rihanna for the unlikely trio’s new single.

The Grammys are on Sunday on CBS, live from the Staples Center. LL Cool J is hosting. You can check out the list of major nominees right here.
