Billboard's 10 Best Grammy Performances, 2000-2013

With tons of musicians scheduled to appear onstage at the 56th Grammy Awards on Sunday (Jan. 26), we're expecting great performances and once-in-a-lifetime collaborations. But this year's event has a lot to live up to, especially considering the unforgettable performances we've seen this millennium so far. Before this year's crop of nominees take the stage, join us in counting down the 10 best Grammy performances from 2000-2013.

9. Gorillaz, Madonna & De La Soul, 2006
The 48th Grammys started off as no other Grammys had before -- with an opening band that wasn't even three-dimensional. Animated act Gorillaz took to the stage to perform the Record of the Year-nominated "Feel Good Inc.," joined briefly by the real De La Soul and a hologram of Madonna. But when the real Madge appeared onstage moments later to perform her 2005 hit "Hung Up," with its sexy dancing and ABBA samples, the Grammy crowd truly let loose.

6. Lady Gaga & Elton John, 2010
Lady Gaga's performance at the 52nd Grammy Awards was classic not only for its over-the-top theatrics, but for Elton John's appearance on "Speechless" and the duo's duet on Elton's classic "Your Song." The best part? The conjoined mega-piano Gaga and Elton played on, not to mention the pair's matching rhinestone glasses.

5. T.I., Jay-Z, M.I.A., Lil Wayne & Kanye, 2009
It was as though a new rap supergroup ("the rap pack" seems fitting) formed at the 2009 Grammy Awards, when all facets of hip-hop joined forces for one killer performance of T.I. and Jay-Z's "Swagga Like Us." Lil Wayne and Kanye West held their own as usual, but it was a pregnant M.I.A. who stole the show in her sheer polka-dot dress. The fiesty diva didn't just look like she was about to pop -- she actually gave birth three days later.

2. Eminem & Elton John, 2001
Eminem infuriated the Gay & Lesbian Alliance Against Defamation with the homophobia-tinged lyrics on his 2000 album "The Marshall Mathers LP," and the organization protested the 2001 Grammys because of his involvement. But gay activist Elton John crossed the picket lines and joined Em's performance of "Stan" at the ceremony in a move that was musically powerful, as well as political.

1. P!nk, 2010
For the 52nd Grammy Awards, P!nk took a page from Cirque Du Soleil's playbook to give a graceful, show-stopping performance of aerial, acrobatic and vocal brilliance. P!nk may not have walked away with any trophies that night, but thanks to her high-flying rendition of "Glitter in the Air," she was the artist everyone was talking about come Monday morning.
