It's a historic day for Mike Stephen as he chats with Craig Pfannkuche of the Chicago and North Western Historical Society about the ambitions of Chicago's first mayor, author Daniel Kay Hertz about his book The Battle of Lincoln Park, and pays a visit to Steve Krakow (aka Plastic Crimewave) to learn about the Secret History of prog-rockers Mugicians. Local music this week is powered by Aurora L'Orealis.
