In a city as boosterish on burlesque as Denver, creativity earns extra bonus points. Every third Monday, the performance troupe behind Merry Widow's Artisan Operetta surprises its audience at Voodoo Comedy Playhouse with a comedic (and clothing-light) tribute to any number of topics from this century and the last — from sultry takes on Roy Lichtenstein and Mae West to a technicolor foray into '90s teen craze Lisa Frank. When it comes to burlesque maven Merry Widow and her troupe's shifting cultural aesthetic, nothing is sacred — and everything is sexy.
