If I was in Chicago I would go to this:

Sonnenzimmer is having a little musical shindig and studio sale at their place tomorrow, Sunday the 14th (Vive la Liberte!) during the day. Which makes this as good a time as any to also mention that their painting and printmaking show at Lula (with Jordan Martins) is also up and is 110% awesome. So what you should probably do is go to both.
