Running time: 60 minutes. $12.  (world premiere) www.theaterforthenewcity.net 212-254-1109  Darkness can be fun - come to the dark side! "Princes of Darkness" is a blending of the Hamlet, Oedipus, and Dracula stories. Your host for the journey is none other than Lucifer. Satan's question is, "If God is so great, why is the world such a mess?" He proposes an unusual and extreme remedy for the problem. The mood of the evening? A shadowy dungeon full of sultry glamor, and a hint of whiskey in the air. The sounds? Tons of Phillip-Glass-sounding stuff, with hints of spaghetti western melodrama a-la-Ennio-Morricone. The movement/dance? The well-known mixture of Klein irony, energy, and a variety of dance genres. This world-premiere is brought to you by the guy who presented "Zombie," the award-winning Off-Broadway play, adapted from the novella by Joyce Carol Oates (www.zombietheplay.com) and the gal who brought you "La Enferma" (www.rachelkleinproductions.com, www.myspace.com/rachelkleinnyc). In "Zombie," Connington played a mild-mannered serial killer. In "Princes of Darkness", he presents Lucifer, a creature of oily charm and devilish plans. Klein builds on her body of darkly humorous work, and has a few new tricks up her sleeve.  This play is part of the "Dream Up Festival"; a theater festival that takes place at the Theater for the New City (TNC) from August 8 to September 5, 2010.
