“It’s going to be a spectacular moment,” says Academy CEO

Last year, Beyonce kicked off the 2014 Grammys with a performance of “Drunk in Love” that was billed anything from flawless to shameless and inappropriate. She is booked to perform at this year’s edition as well, taking place this Sunday.

However, expect no rubbin’ and gridin’ and no Jay Z cameo, President and CEO of The Recording Academy Neil Portnow tells E! News at the Billboard Power 100 Celebration in Beverly Hills.

Beyonce is not an artist who’s gotten to where she is today by being stuck in the same routine, even concerning her live performances. So for the Grammys 2015, she is preparing a performance that will be “dramatically different than anything [we’]ve seen her do in a long time,” Portnow explains.

He wouldn’t say what he meant by that, but that makes sense because he wants it to be a surprise. “It's really going to be a spectacular moment for us and for her for sure,” he teased.

Portnow is convinced, from what he’s seen in rehearsals so far, that this year’s Grammys will be the most memorable edition of all time, not just because of the A-list performers but also thanks to the duets planned.

Viewers at home should expect live acts from Beyonce, Katy Perry, Pharrell, Madonna, Miranda Lambert, Ariana Grande and Kanye West, but also duets from Sam Smith and Mary J. Blige, Sia and AC/DC, Lady Gaga and Tony Bennett, Jessie J and Tom Jones, Adam Levine and Gwen Stefani.

Rihanna will also perform her new song “FourFiveSeconds” for the first time live, and will be joined on stage by Kanye and Sir Paul McCartney.
