If you’re a music lover, one of the highlights of this year’s Chicago Humanities Festival is a cabaret style performance highlighting the music of Josephine Baker, Eartha Kitt, Tina Turner, and Nina Simone. All four of the singers moved abroad — either to ride out their fame, or to enhance their creative process. It was outside the U.S. where their repertoires took on a whole new life. Rob Lindley is one of the theater directors behind this cabaret. He discusses the cabaret with Lili-Anne Brown, an actress, performer and director — and the host of Four Women.(Flickr/Glenn Robinson, Allison Marchant, scarlatti2004, Heinrich Klaffs)
