We all love Labor Day Weekend. After all, what would the world be without labor unions, right? Now that we've established the importance of organized labor movements, let's talk some jazz. The great jazz legend Duke Ellington died in the summer of 1974. A few weeks later, a number of musicians came together in Grant Park and held a small music festival in his honor. The celebration was held again the next year and the year after that, and the year after that, and so on. Crowds kept multiplying each time. In 1978 the first official Jazz Festival was held in Chicago. This year we celebrate the 33rd Annual Chicago Jazz Festival in various locations around the city starting Thursday September 1st through Sunday the 4th. It kick starts on Thursday at the Chicago Cultural Center, on Friday evening it moves to the Millennium Park and Saturday and Sunday performances will be held in Grant Park. Some of the acts this year include two-time Grammy Award winner Roy Hargrove; vocalist, songwriter producer Cassandra Wilson, Randy Weston and many more. Best of all, admission to this event is free!
