Muse have signed up to perform as the headline act at this year’s War Child Brit Awards Concert.

The gig takes place two nights before the Brits music awards bash and marks the start of charity War Child’s 20th anniversary.

Muse, who wrote and recorded the official London 2012 Olympic Games song Survival, are nominated for best British Group and British Live Act at February’s Brits, where War Child will get a Special Recognition gong.

The band’s frontman Matt Bellamy said: “We are proud to have a continuing association with War Child, who have been doing amazing work over the last 20 years.

“It’s great to see their efforts being recognised at this year’s Brits and we are really looking forward to playing this special show for them.”

The Brit Awards Concerts have raised more than £600,000 in the last four years, with performances from Coldplay, The Killers, Blur, Kasabian, Ed Sheeran and Mark Ronson.

All proceeds will go towards War Child’s work with children in war zones around the world.

Ben Knowles, the charity’s director of fundraising and music, said: “This year is a special one for War Child and we’re delighted to welcome one of the world’s biggest and best live bands play for us to launch our 20th anniversary year and celebrate the important award we are winning.”

The London gig, which will feature another act yet to be announced, takes place at the 02 Shepherd’s Bush Empire on February 18.
