A couple of weeks ago, Erica and I went to the Metro and saw K'naan -- a Somali-Canadian rapper. The show was great, but a particular highlight was when he brought out Kate (aka K8DS) a 13-year-old from Chicago who puts up videos on YouTube of herself playing guitar and singing. Someone had sent K'naan her covers of his songs and so he invited her to come be part of the show. She sang Be Free with the band backing her and then stayed to accompany him on Fatima. It just makes me smile.
