On this edition of Two Way Street, we talk with the directors and stars of two classics of American theater that are on stage in Atlanta now: First, director Freddie Ashley, and actors Deborah Bowman and Kevin Harry join us for a conversation about Stephen Sondheim’s dark, satiric masterpiece “Sweeney Todd; the Demon Barber of Fleet Street.” It’s playing now at Actor’s Express Theatre. For more information, go to their website. Then, we talk to director John Dillon and actor Neal Ghant about the production of David Mamet’s “American Buffalo.” Mamet wrote the show in the mid-1970s. It’s the play that put him on a fast trajectory to becoming recognized as one of the finest American playwrights of his generation. The show is being mounted by Kenny Leon’s True Colors Theatre.
