Who's Performing At The 2015 Oscars?

It is fast approaching: The Oscars air this Sunday, Feb. 22. They're the 87th annual Academy Awards, so by now I think it's safe to say that we generally know what to expect: Some winners and losers we don't agree with, presenter banter that volleys between charming and unbearably stilted and awkward, and a dash of the unexpected. Oh, and music, whether it comes from high-concept musical numbers, the in memoriam segment, or the traditional performances by the Best Song nominees. But, who's performing at the Oscars this time around? There are some great names lined up, from Anna Kendrick to something very vague from Jack Black.

In fact, a lot of what's going down at this year's Oscars is being kept pretty vague — we know largely who's taking the stage, bust aside from the fact that Harris will be performing a song by "Let It Go" writers (and last year's Best Song winners) Robert Lopez and Kristen Anderson-Lopez called "Moving Pictures" that will take on multimedia aspects, we don't know much other than that the songs nominated for Best Song will be performed as usual. It's entirely possible all the performers whose role in the ceremony is being kept vague will join Harris during "Moving Pictures," which would be pretty epic. But we don't really know.

But we do know, for the most part, who will be performing. So here's who you can expect to take the stage in a musical fashion come Sunday night:

Neil Patrick Harris

Let's knock the obvious one out right off the bat. Harris is hosting this year's shindig, so there's no doubt he'll be making good use of everything he learned as a four-time Tony host by making this a pretty musical night.

Anna Kendrick

It hasn't been revealed exactly what she'll be performing yet, but Kendrick will definitely be performing during the ceremony. Pretty much all we know is that it will be "something special that is sure to be an "only on the Oscars" moment." Magically cryptic?

Adam Levine/Maroon 5

They'll be taking the stage for a performance of "Lost Stars" from Begin Again , one of the songs nominated for tunes nominated for Best Original song.

Tegan & Sara With The Lonely Island

I am looking forward to this one quite a lot: These awesome folks will be taking the sage to perform "Everything Is Awesome" from The LEGO Movie .

And lo, everything will be awesome.

Rita Ora

Ora will be performing "Grateful" from the soundtrack to Beyond the Lights . Let us be, er, grateful l that that this underrated movie's being honored at the very least with a performance and a Best Song nomination.

John Legend and Common

These two will be performing heir Golden Globe-winning song "Glory" from Selma.

Tim McGraw

He's singing the song "I'm Not Gonna Miss You" from Glen Campbell: I'll Be Me. 2006 He'll be performing in Campbell's place, as Campbell is suffering from Alzheimer's.

Lady Gaga

Hers has been dubbed a "special tribute performance." VAGUE.

Jack Black

According to Deadline Black's is a "very special sequence." AGAIN WITH THE VAGUE.

Jennifer Hudson

They are trying to kill me with all of this vagueness: Hudson's is also billed as a "special performance" with no other details. Perhaps she'll team with Kendrick? Maybe she'll do a reprise of that amazing "And I Am Telling You" performance? Or is too soon for that?
