All eyes on Frank Ocean as Grammy Awards kick off

London-based folk-rockers Mumford & Sons had one of the top-selling albums of the year with "Babel" and already has a history with The Recording Academy's thousands of voters, having been nominated for major awards the year prior. Also, The Black Keys have a winning track record at the Grammys.

And don't count out West and Jay-Z, who were shut out of the major categories but remain very much in voters' minds.

Jack White's "Blunderbuss" competes with fun.'s "Some Nights," Ocean's "channel ORANGE," Mumford's "Babel" and The Keys' "El Camino" for the night's top award, album of the year.

Gotye's "Somebody That I Used To Know," featuring Kimbra, Taylor Swift's "We Are Never Ever Getting Back Together" and Kelly Clarkson's "Stronger (What Doesn't Kill You)" join the fun., Ocean and Black Keys entries in record of the year.

Fun. and Clarkson also are nominated for song of the year along with Ed Sheeran's "The A Team," Carly Rae Jepsen's "Call Me Maybe" and Miguel's "Adorn."

And rounding out the major categories, fun., Ocean, Alabama Shakes, Hunter Hayes and The Lumineers are up for best new artist.

Those major nominees figure prominently on the 3 1/2-hour telecast, broadcast live on CBS.

Swift will kick things off with a show-opening performance. Fun. and Ocean will take the stage. Others scheduled to perform include Justin Timberlake, Carrie Underwood, Clarkson, White and Juanes.

There will be no shortage of mashups the Grammys have become famous for, either. Elton John, Mavis Staples, Mumford, Brittany Howard, T Bone Burnett and Zac Brown are saluting the late Levon Helm, who won the Americana Grammy last year a few months before his death. The Keys will join Dr. John and the Preservation Hall Jazz Band on stage. Sting, Rihanna and Bruno Mars will perform together. Other team-ups include Miranda Lambert and Dierks Bentley, and Alicia Keys and Maroon 5.
