In many ways, the Jazz Fest is the top dog of Labor Day festivals. It’s one of the oldest (established in 1980) and is probably the biggest of our end-of-summer shindigs, and every year it offers some big names, as well as some backward-looking tributes, and programming that embraces everything from the cool jazz you know to the inclusive global music jazz has become. It’s the world’s largest jazz festival that’s free and open to the public. No wristbands, no admission fees, no lines for tickets. Just show up and be wowed by the more than five-dozen acts taking the stages. The lineup includes Herbie Hancock, Regina Carter, Wayne Shorter Quartet, George Benson, and Benny Golson.
