The Black Keys, FUN., Mumford & Sons, Rihanna, and Taylor Swift -- all Grammy nominees this year -- are the first performers announced for the 55th Annual Grammy Awards. The live broadcast, hosted by LL Cool J, is set for Feb. 10 at 8:00 PM (ET/PT) on CBS. Additional performers and presenters will be announced in the coming weeks.

"Grammy week is really unlike anything else. It is full of excitement, anticipation, nerves and anxiety. [It's] ultimately the most exciting night in music," says Taylor, a two-time nominee this year. "To get to be a part of it for a few years now is such a treat. It's the most amazing circus you could ever see!"

FUN., Mumford & Sons, Jay-Z, Frank Ocean, Dan Auerbach and Kanye West lead the pack of nominees with six nods apiece. Country music's own Hunter Hayes has three nominations including the all-genre Best New Artist category. See a list of 2013 Grammy nominees here.
