Nina Gordon, and OK she's on Warner Brothers now and moved away from Chicago but she used to be Veruca Salt and does the best version of "Straight Outta Compton" you can EVEN imagine (thanks Dan!!!!): http://download.wbr.com/mirror/ninagordon.com/media/sounds/covers-straig...
Got others? List 'em here, but make 'em good.
The Dials - linky
Bang Bang - linky
I'd also list The New Black, but Liam up and moved to New York, so I don't think they're technically a band anymore, but they were still good.
Chin Up Chin Up is a band full of dudes, but they have great lady vocals at times, but I have no idea who she is. I'm too lazy to do any more internet digging. I like 'em though.
Oh, and The Ponys, too.
