Grammy Nominations Concert Preview: Taylor Swift, Maroon 5, More!!

MTV News breaks down what you should expect from the big show on Wednesday night.

There's only a few hours to go until the "Grammy Nominations Concert Live!!" airs from Music City. And in addition to revealing who will be up for Grammy Awards in 2013, the show is sure to entertain. The Recording Academy has locked in an unlikely pair to co-host and performers from all walks of life to hit the stage at the Bridgestone Arena in Nashville.

First up, let's take a look at the hosts. LL Cool J is back to help emcee the event, and this year he's joined by veteran Grammy performer Taylor Swift, who is sure to add some country sparkle as the show goes live from her homebase. For anyone wondering if they'll hit it off, the twosome has already proved to have some chemistry when they appeared in a Grammy ad at the top of the year.

With Swift on hosting duties, one big question remains: If One Direction ends up with a Grammy nod, could she end up shouting out her rumored love interest Harry Styles during the show? Fans can tune into the concert special on CBS at 10 p.m. ET/PT to find out.

In addition to the show's A-list hosts, they also have enlisted a mix of Grammy newcomers and show vets to perform.

The concert will host not only Nashville darlings like the Band Perry and Dierks Bentley, but will also add some rock, pop and R&B flavor to the mix thanks to appearances from Maroon 5, Ne-Yo, and the Who. All these acts have been nominated, won or performed at the Grammy Awards over the course of their careers.

And, as Ne-Yo shared with MTV News last weekend, he might use the event to hash out some album-title drama with Swift. " I can honestly say that even though I don't believe in accident or coincidence, it is completely coincidental that we keep winding up in the same places, even that our album titles are similar," he said about his album named R.E.D. and hers named Red. "It's completely coincidental, but like I said, I don't believe in coincidence, so it's got to mean something."

Then there are the new kids on the Grammy block. 2012's breakout band Fun. (and Janelle Monáe), Nashville's answer to Justin Bieber Hunter Hayes, and country music chart-topper Luke Bryan will all storm the Grammy event for the first time in their careers, perhaps signaling the fact that they just might score themselves a nomination or two.

Once the show wraps up on Wednesday night, the nominees will only have two months to prep for the big event. The 55th annual awards show will air live from the Staples Center in Los Angeles on Sunday, February 10.
