Mike Stephen talks with CD Baby CEO Tracy Maddux about the DIY Musician Conference coming to Chicago next weekend, checks in with Plastic Crimewave (aka Steve Krakow) about 1980s new wave band the The Arms of Someone New for this week’s edition of The Secret History of Chicago Music, and chats with Thrift & Thrive co-owner Joe Basilone about not buying anything for a year and now dominating Irving Park Road with two more businesses — Perkolator coffee and Sputnik Books & Records. Meanwhile, we discuss how Wrigleyville has changed over recent years and the strict new neighborhood rules during the Cubs’ home playoff games. This week’s local music is provided by The Forest of Love.
