Orton Park Festival

From Orton Park Festival Website:

One of the country's longest-running outdoor music festivals, Orton returns with four days of festival fun in the heart of Madison's east side. This MNA-sponsored event is known for great music, an array of terrific vendors from local restaurants and businesses, kids games, an elegant Jazz Brunch, a rather quirky auction, and magical aerial trapeze performances under one of the park's great oaks.
