On this edition of The Arts Section, host Gary Zidek visits a Chicago Sinfonietta rehearsal for its annual Martin Luther King Jr. concert. Gary talks to to the orchestra’s assistant conductor Jonathan Rush about the special program. Later, Gary sits down with Chicago Magazine dining editor Amy Cavanaugh for a conversation about this year’s Chicago Restaurant Week line-up. The Dueling Critics, Kerry Reid and Jonathan Abarbanel, review Steppenwolf Theatre’s new play DANCE NATION. And Gary revisits a story he did three years ago on Academy Award-winning composer Justin Hurwitz, as WDCB prepares for a special LaLa Land screening. All that, plus the weekly Arts Section calendar.
