The 54th annual Grammy Awards ceremony airs on CBS this Sunday night at 8 p.m. ET/PT, and rock fans have quite a few reasons to watch the telecast.  Not the least of these is the Foo Fighters , who will compete for trophies in six categories, including Album of the Year, Best Rock Album and Best Rock Song.  Other rock-related acts with multiple nominations include Skrillex , with five nods; Mumford & Sons and Bon Iver [bohn ee-VAIR], with four each; and Coldplay and Radiohead , with three apiece.

This year's Grammy Awards only have 78 categories, compared with the previous 100+ categories of previous years.  But don't expect the extravaganza to wrap up earlier than usual.  "No, the show won't be shorter," laughs Ken Ehrlich , the executive producer of the Grammy Awards.  "We've taken categories out but we haven't figured out how to make it shorter!  There's just so much good stuff out there that we want to celebrate."  That means viewers will see a whopping 19 performances spread over the three-and-a-half-hour show and, as in past years, most of the actual trophies will be handed out in a non-televised ceremony that takes place beforehand.

In fact, according to Ehrlich, the Grammys Awards show isn't so much about the actual awards as it is about the performances, which feature cool collaborations from artists in every musical genre, including quite a few big names in the world of rock.  This year's telecast will feature:

- Bonnie Raitt and Alicia Keys paying tribute to Etta James
- Coldplay performing "Princess of China" with Rihanna
- The Beach Boys teaming up with Foster the People and Maroon 5
- Foo Fighters doing a tribute to dance music with Chris Brown , Lil Wayne and David Guetta
- Additional performances and appearances from Bruce Springsteen and the E Street Band , Paul McCartney and Joe Walsh .

Explaining why so many stars are willing to give up the solo spotlight to team with other artists for these special "Grammy Moments," Ehrlich tells ABC News Radio, "A great number of [these artists] go on other shows and perform well, but we look at our show as being what you're working towards.  You want to be the best on this show because it means something to be the best on this show.  And so there's this kind of mindset that allows them to be more collaborative."

Each year, the most prestigious awards -- known as the Big Four -- are Record of the Year, Song of the Year, Album of the Year and Best New Artist.  Here's the difference between Record and Song of the Year: the Song of the Year Grammy goes to the song's writer or writers, who are not necessarily the same ones who performed the tune.  The Record of the Year Grammy goes to the artist, producer, engineer and mixer of the song.  For Album of the Year, the Grammy goes to the artist, the album's producer or producers, the engineers and any featured performers.
