Mike Stephen visits with Frank Lloyd Wright Trust curator David Bagnall about FLW's architectural legacy in the 150th anniversary year of his birth, checks in with Slow Roll Chicago co-founder/vice president Jamal Julien about promoting social change in Chicago via riding bicycles, and chats with Plastic Crimewave (aka Steve Krakow) about 1980s power-pop wizard Julian Leal for this week's edition of The Secret History of Chicago Music. Meanwhile, we read Mike's t-shirt, discuss how Walgreens is wrongly applying the Cook County soda tax to LaCroix Sparkling Water, and talk about the new boozy Taco Bell just off the Magnificent Mile. This week's local music is provided by Sunjacket.
