Chicago Band Map & Atlases at 1st A.V. Fest September 8, 2011 Unless you’re some sort of magic snowman reading this blog in a Wi-Fi equipped freezer somewhere, you probably don’t want summer in Chicago to end. Part of the problem of losing the warm weather is it means we have to temporarily say goodbye to the gajillion music festivals that take place here. But before winter hits and the magic snowmen reclaim the streets, the pop-culture/entertainment website The A.V. Club is bringing us one more outdoor festival.
