Hurricane Sandy effected the entire Tri-state area around New York City, leaving millions without power and displaced from their homes. The storm, which touched down around Halloween, is still at the forefront of our minds.

Pop stars did their part and performed at the largely classic rock-leaning 12-12-12 concert event that took place at New York City's Madison Square Garden on Dec. 12. Kanye West and Alicia Keys were on hand to lend their talents for good, as was Coldplay frontman Chris Martin.

Keys was the first artist who performed at around 10 PM. Looking lovely in a red jumpsuit with a halter top and her angled bob, which is growing out beautifully and now boasts a blonde streak, began her set performing 'Brand New Me' while seated at the piano.

She said, "I was born and raised in New York City. I still live down the street, in New York City... I love my city. Tonight, we're here to celebrate love and life." She asked the audience to light up MSG by bringing out their cell phones while she sang 'No One.' Later on, at the very end of the show, she came out to sing her rousing chorus in Jay-Z's 'Empire State of Mind.'

West took the stage around 11:15 PM, as the only rap act of the night. He kicked off with 'Clique' and he wore a hoodie and a black leather... kilt. He paired his skirt  -- well, kilt, if you prefer -- with pair of leather pants while he popped off hits. Did he raid girlfriend Kim Kardashian's kloset before the event?

While rocking the stage with his DJs, West also performed 'Power,' 'Jesus Walks,' 'Runaway,' and 'All of the Lights.' He also ripped through 'Golddigger' and 'Stronger,' getting the crowd pumped, and slipped in a little of Rihanna's 'Diamonds' and 'Mercy.'

The camera didn't pan to the crowd much, since it's likely not West's demographic. However, Keys and West certainly represented the pop and R&B genres well.

Chris Martin of Coldplay was also on hand to perform solo, strumming guitar in a dark and gentlemanly suit. He sang 'Viva La Vida' and more. He joked, "I know you wanted One Direction, but it's way past their bedtime." R.E.M. singer Michael Stipe also came out of retirement for the event, joining Martin for a rendition of 'Losing My Religion.'
