So, I'm going to run a Jenga Dread (do I still have to say that?) one-shot for my regular D&D group, who are totally cool with it. The story begins with a former group of roleplayers called back to their home town after 20 years because of the suicide of their former GM. Turns out that their last campaign actually cracked open a gate through which Our Lady of Darkness is just now emerging. The GM (Dave) has been looking for a way to seal the gate for almost those entire 20 years, and the only thing that has kept him together that long is literally bleeding the crazy away. (Or at least that's what he says in the pre-recorded video message.)
I'm pretty confident of the questionnaires and the general outlines of the story (I'm a very improv-heavy GM, so I feel good about working around a vague outline with a lot of notes for potential situations). However...
...at some point, I'd like to trigger a playlist of spooky/disturbing music (from creepy blues to occult metal, whatever) that the characters can't turn off. It's one aspect of ramping up the tension that I'd like to implement. Please, all, suggest songs for the playlist! It won't be played too loud in the real world, but will be described as increasing in volume in the fictional space.
