The best new artist nominees teamed up with soul luminary Stevie Wonder for a spirited run-through of their hit "Burnin' Up," followed by an equally kicky take on Wonder's "Superstition."
Miley Cyrus & Taylor Swift
The teen stars – and apparent BFFs – teamed up for a tender acoustic moment, singing Swift's "Fifteen" live for the first time.
M.I.A., Jay-Z, T.I., Lil Wayne & Kanye West
Calling themselves the "rap pack" – the superstars joined forces for a stylish version of "Swagga Like Us," featuring a live performance by the pregnant (in her ninth month) M.I.A.
Radiohead
Backed by the University of Southern California marching band, the Brit alt-rockers provided one of the Grammy's most galvanizing rhythmic highlights with their skittish, angular "15 Step."
Adele & Jennifer Nettles
Best new artist winner Adele had orchestral backing for her smoky, soulful "Chasing Pavements," but things really heated up when the Brit was joined by Sugarland's Jennifer Nettles, who already collected several Grammys, on her nominated song.
