Jack Helbig's article on the new Richard Greenberg play, The Violet Hour [May 9], was the most interesting and in-depth look at the play I have read. But what made this article such a good read was the analysis and insight into the playwright. However, for all of his knowledge of Greenberg, Helbig got one thing wrong. Steppenwolf has put on a production of Greenberg's since 1999. In 2002 Steppenwolf put on a wonderful production of The Dazzle. Just thought you might like to know.
