"Express Yourself" is not just one of Madonna's hit songs, it is also the rallying cry for her new project Art for Freedom.
She is inviting fans to submit original video, music, poetry and photography to fight oppression, intolerance and complacency through art.
Madonna told Anderson, ""I'm encouraging other people, whether they're professionals or not, to use their creativity to express themselves, to get a conversation going, to get the party started."
