The 2013 Grammy Awards keep getting better and better. The list of nominees, which was announced last month, is full of indie and alt-rock acts, and now three of those bands -- the Black Keysfun. and Mumford and Sons -- are among the artist that have signed on to perform during the 55th annual ceremony, which will take place on Feb. 10 in Los Angeles.

This will be the first Grammy performances for the Keys and fun., while Mumford and Sons will be returning for the first time since their all-star jam alongside the Avett Brothers and folk-rock icon Bob Dylan at the 2011 ceremony. The set that night included Mumford running through their own tune 'The Cave,' followed by the joint Avett/Dylan hootenanny-style stomp through the Dylan classic 'Maggie's Farm.' If you missed it -- and even if you didn't -- it's definitely worth watching here.

The Black Keys ('El Camino'), fun. ('Some Nights') and Mumford and Sons ('Babel') are among the bands facing off for the prestigious Album of the Year honors at the 2013 Grammys. Fun., the Mumfords and the Keys' Dan Auerbach are each nominated for a total of six Grammys at this year's Awards, while the Keys themselves are up for five. The 55th annual Grammy Awards will be broadcast live from the Staples Center in Los Angeles on CBS at 8PM EST on Feb. 10.
