On this edition of The Arts Section, host Gary Zidek catches up with the curator behind a new traveling photo exhibit on Princess Diana that’s on display in Oak Brook. Dueling Critic Kerry Reid stops by to discuss a new musical revue that celebrates the sounds of the 70s. Later in the show, Gary talks with the artistic director of Pegasus Theater about the company’s 35th annual Young Playwrights Festival, which just kicked off. Then a look inside an exhibit that sheds some light on a long lost local architectural treasure. And we’ll look back at the life and career of the late, great Sidney Poitier.
