K'naan and Nelly Furtado Link Up on 'Letterman'

K’naan joined forces with a bespectacled Nelly Furtado on Thursday’s “Late Show with David Letterman.” The fellow Canadians performed “Is Anybody Out There?,” their collaboration off K’naan’s EP More Beautiful Than Silence, for the first time live. Both artists have new projects on the way. K’naan’s third album Country, God or The Girl is set for release on May 1, while Nelly is readying T.S.I., the follow-up to her 2006 English-language album Loose, for the summer.
