I've had this idea for a while now but have not been able to find the content.
It's based on the *dark theatre* idea sorta Anne Rice-Vampire theatre-Paris. There would be a main show (very sexy but tame) as well as different rooms where there would be darker activities going on. Behind the scenes...Dressing room, Prop room, Back Alley, theatre after hours etc would all have various dark debauchery scenes playing out. I foresee it as hardcore but it could also be suggestively softcore, with lots of costume/props. Very rich and lush and dark. Something like the movie Moulin Rouge in its feel.
