Frank Ocean, Maroon 5, Alicia Keys To Play Grammys

Ocean will make his first public appearance on the February 10 show since last weekend's altercation with Chris Brown.

Whether he's got two good hands or not, Frank Ocean has been added to the roster of Grammy performers. The singer, who claimed he injured one of his hands in a weekend studio fight with Chris Brown, will take the stage for the first time at the February 10 awards show along with newly added performers Maroon 5 and 14-time Grammy winner Alicia Keys.

The 55th annual show is already slated to feature sets from Justin Timberlake,
 Fun., Taylor Swift, Jack White, the Black Keys, Lumineers, Mumford & Sons, Elton John with Ed Sheeran, Carrie Underwood, Dierks Bentley and Miranda Lambert.

The first roster of presenters has also been announced, and it includes Katy Perry, Neil Patrick Harris, Kaley Cuoco, Faith Hill, Carly Rae Jepsen, 
Tim McGraw and Keith Urban.

One of the leading nominees this year, Ocean is up for six awards, including Record Of The Year for "Thinkin Bout You," Album Of The Year and Best Urban Contemporary Album for Channel Orange, Best New Artist and Best Rap/Sung Collaboration (with Jay-Z, Kanye West and The-Dream) for "No Church In The Wild."

Three-time winners Maroon 5 are vying for two Grammys this year, for Best Pop Duo/Group Performance for "Payphone" and Best Pop Vocal Album for Overexposed.

The mystery surrounding Ocean's performance will be whether the reclusive singer will make any statement about Sunday's parking lot altercation
 with Brown, which Los Angeles Sheriff's deputies are still investigating.

Both Brown and Ocean are Grammy nominees and while Brown has not been named as a potential performer, Ocean tipped his hat before Thursday's (January 31) official announcement that he would be singing on the show when he tweeted about a post-fight injury to his finger that means, "I can't play w/two hands at the Grammys."

The Recording Academy will extend the weekend's activities with a one-hour special on February 9 entitled "The Grammys Will Go On: A Death in the Family." The show looks at how Grammy producers, hosts and musical artists made last-minute changes
 to the February 2012 program in the face of the death of Whitney Houston. The special will use never-before-seen rehearsal footage and behind-the-scenes interviews with artists and the Grammy production team to look at the 48 hours leading up to last year's show, which was thrown into turmoil with Houston's passing 24 hours before the telecast.

Among those giving their personal accounts are: Clive Davis, Dave Grohl, Jennifer Hudson, host LL Cool J, Bruno Mars, Katy Perry, Bruce Springsteen and Taylor Swift.
