12-12-12 Concert for Hurricane Sandy Relief: Kanye West, Alicia Keys Perform

Alicia Keys and Kanye West joined an all-star line-up last night as part of the 12-12-12 concert for Hurricane Sandy relief at New York City's Madison Square Garden.

Outfitted in a gorgeous red dress and her new bob haircut, Alicia performed a medley on the piano including 'Brand New Me' from her 'Girl On Fire' album. The native New Yorker also took fans back with her classic 'No One' as well as the mega-collaboration 'Empire State of Mind' sans Jay-Z.

Kanye took the stage for his own one-man medley of songs like 'Golddigger,' 'Mercy' and 'Runaway.' Always the fashionista, it was Ye's ensemble of a black leather kilt and a Pyrex hoodie that really set social media abuzz.

Rapper Cam'ron even commented, and later deleted, on Instagram: “Pyrex and a skirt? S--- ain't adding up. And if u co-sign this I'm blocking u!! Straight up. I'ma have to save us.”

In addition to Keys and West, The Rolling Stones, The Who, Billy Joel and Chris Martin also performed in hopes to raise continued awareness and funds for the storm-ravaged Eastern Seaboard.
