“The Wizard of Oz: A Jazz Musical for All Ages” is a magical experience for young (and young-at-heart) audiences. The production is based on MGM’s classic motion picture, with its timeless score and eternal allegories, and is enhanced by jazzy arrangements. It follows John Kane’s adaptation for the Royal Shakespeare Company, which is based on the book by L. Frank Baum, with brilliant songs by lyricist E.Y. (“Yip”) Harburg and composer Harold Arlen. The cast is multi-racial and features Latino, Black and Asian actors, fulfilling Yip Harburg’s vision of a multicultural universe. Presented by Harlem Repertory Theater and Yip Harburg Foundation, directed by Keith Lee Grant.
