Coldplay Performs "Atlas" Live in London

From Rolling Stone:

After a botched start that included a round of "Fix You," Coldplay's Chris Martin led his band into their first-ever live performance of "Atlas" last night in London. The song is Coldplay's contribution to the The Hunger Games: Catching Fire Soundtrack.

Bathed in blue light, a very sweaty Martin looked relieved as the band kicked into the song together. As he began singing the opening lines – "Some saw the sun, some saw the smoke" – the audience joined in just as loud. As the song built, Martin sang "carry the world" while guitarist Jonny Buckland coaxed some plaintive notes from his instrument. The performance went so well, unlike that of their previous song, that Martin jumped up from his piano with an ear-to-ear smile and did a little victory lap on the stage.

The performance was part of an event Coldplay organized called "Under 1 Roof," and it also featured sets by Lily Allen, Robbie Williams and Ricky Gervais as his Office character David Brent, among others. The concert benefitted Kids Company, a U.K. organization that provides "practical, emotional and educational support to vulnerable inner-city kids."
