Many regular customers of Boulder's Dinner Theatre stayed away from Cabaret. The show's seedy settings, writhing dance numbers and uncomfortable focus on fascism clearly set it apart from most BDT fare. But in a just world, it would have attracted dozens of people who normally never set foot in a conventional dinner theater. Director Michael J. Duran's production was a visceral treat, with fantastic music, deft staging and vivid, all-stops-out performances. Brian Mallgrave, with a fresh take on the familiar Emcee character, and Alicia Dunfee as Sally Bowles were especially good.
