The deadly January attacks on the French satirical newspaper Charlie Hebdo and a Jewish food market have given this year's Jazz Day added significance, according to pianist Hancock. "Jazz has been a bridge for bringing people together," UNESCO Goodwill Ambassador Hancock told Associated Press. "It's not sectarian and it's not just for people of a particular ethnic group. It's for human beings. We need to recognise that which makes us similar, while at the same time honoring that which makes us different. It will bring a positive message."
