Billboard.com's Best Pictures of 2011
Foo Fighters, Lollapalooza, August 2011.

For the sake of the Grammys, Dave Grohl is squelching his beef with electronic music.

The Foo Fighters, who have been known to diss computer-made tracks and their creators during their live shows, will participate in a "special performance highlighting dance/electronica music" at Sunday's (Feb. 12) show, according to an official Grammys press release issued this afternoon (Feb. 7). The rockers' collaborators in this ode to dance music? An unlikely bunch that includes Chris Brown, Lil Wayne, David Guetta and Deadmau5. All five artists are nominated for Grammy Awards this year, with the Foo Fighters up for the coveted Album of the Year category with their "Wasting Light."

It's worth noting that Deadmau5 is not that surprising as a Foo Fighters collaborator -- the DJ is nominated for a Grammy with his remix of the Foos' 2011 single "Rope," of which Grohl has admitted he's a fan. (One could speculate that the "Rope" remix may be incorporated into Sunday's collaborative performance.)

It was anonymously confirmed to the Associated Press just this morning that Chris Brown would return to the Grammy stage following a three-year absence from even attending the awards show, though it was not stated at the time in what capacity.

Grammy performers continue to be announced ahead of the awards' live show on Sunday. Just today, Tony Bennett's duet with Carrie Underwood and an Etta James tribute led by Bonnie Raitt and Alicia Keys were both announced.

The Grammys announced last week that Adele will make her first performance after undergoing vocal-cord surgery, in addition to the announcement that Bruce Springsteen and The E Street Band will take the stage. Previously announced Grammy performers include: Katy Perry, Jason Aldean, Kelly Clarkson, Glen Campbell, The Band Perry, Blake Shelton, Coldplay, Rihanna, Foo Fighters (though not known in what capacity until now), Bruno Mars, Paul McCartney, Nicki Minaj and Taylor Swift.
