End of summer trip - venues to visit?

I am planning a road trip vacation at the end of August/ early September.
I am looking for suggestions for places to visit for food/drink/music. I would love to find some good blues or country along with some good brew.

The places that are firm are Chicago on Sep 2 & 3 , Indianapolis on Aug 26 and Milwaukee from August 28 to Sep 1.

As I nail down more dates I will post em.

Thanks
