Of course it's the heartland ...it ain't Canada!
Here are some options. There are many more but these are a few that come to mind immediately:
The Cabooze on the West Bank has live music about every night. Caters to the University age crowd with 18+ nights but the crowd is generally diverse - depending on the bands.

http://www.famousdaves.com/musicclu.cfmThe Front Porch Swingin' Liquor Pigs play at the Eagles club at 25th and 25th every Friday from 7 - 9. They usually have good bands following. The Pigs have a good crowd of regulars.
Mayslacks is a good spot for some garlic roast beef and live music.

If you need more, just ask. Enjoy your stay and bring your parka. This weather sucks lately!
