On this edition of The Arts Section, host Gary Zidek goes behind the scenes of Chicago Sinfonietta's production of ASK YOUR MAMA.  The production comes from Emmy Award-winning composer Laura Karpman and is based on Langston Hughes' epic 1961 poem of the same name.  Gary also talks to filmmaker Alexandra Dean about her new documentary BOMBSHELL THE HEDY LAMARR STORY. The film highlights the former Golden Age movie star's fascinating life. The Dueling Critics, with guest reviewer Catey Sullivan, review Steppenwolf's new production BLKS. And later in the program, Gary chats with author Chloe Benjamin about her new novel, THE IMMORTALISTS. All that plus this week's Arts Section calendar.
