Updated, 8:25 a.m.: Radiohead has been added to the performing line-up for the Feb. 8 Grammy Awards in Los Angeles, joining the likes of Katy Perry, Lil Wayne, Carrie Underwood and fellow Brits Coldplay. Radiohead, nominated for album of the year for "In Rainbows," has been quite the Grammy booster in 2009, with singer Thom Yorke appearing in a television and print ad campaign to hype the Recording Academy-hosted gala.

Indie-focused website Pitchfork reported the news Sunday evening, and a Recording Academy statement confirmed it this morning. Paul McCartney was also added as a performer, and the former Beatle will be joined by Dave Grohl, as nary a Grammy event shall happen without the presence of a Foo Fighter. With Radiohead in, all but two of the album of the year candidates will be on board for the telecast.

It's rare that an artist up for the top prize would not make some sort of live music appearance on the Grammy telecast. However, that's precisely what's happened with Radiohead in the past. The act has been nominated for album of the year twice -- for "OK Computer" and "Kid A" -- but did not perform in either year.
