When you think about listening to jazz, you probably envision yourself sitting in a small, dark, crowded club, like the ones where jazz greats established one of America’s truly original art forms. But listening to jazz outdoors is a fitting way to enjoy an art form that constantly seeks freedom and defies boundaries. You can do just that starting this Sunday in Tyler Park. Jazz duo Carly Johnson and Craig Wagner kick off the festival with their vocal and guitar talents. Sept. 20 features Squeeze-bot, an eclectic mix that defies categorization, lead by Todd Hildreth on accordion. The last date, Sept. 27, is reserved for the University of Louisville Jazz Ensemble, featuring Jim Lewis. This is a family-friendly event. Bring your kids, your dogs and some chairs.
