British pop band Florence and the Machine , U.S. pop singer Colbie Caillat , pianist Herbie Hancock  and singer-songwriter Elvis Costello  will also perform at this year's Nobel Peace Prize Concert in Oslo, organizers said Thursday.
Academy Award-winning actor Denzel Washington will host the show on Dec. 11, a day after the award ceremony in Oslo. "I am honored to attend the Nobel Peace Prize Concert this year and participate in this historic and momentous event to help spread the message of global peace," Washington said in a statement.
Last year, American rap artist and actor Will Smith  and his wife, the actress Jada Pinkett Smith hosted the Nobel Peace Prize Concert, honoring the 2009 peace prize laureate and Smith fan Barack Obama.
The winner of the 2010 Nobel Peace Prize will be announced in Oslo on Oct. 8. The award is always handed out Dec. 10, the anniversary of prize founder Alfred Nobel's death in 1896.
