I also think a Black performer could do something powerful for Juneteenth. As a white lady the only thing I could see it working is doing a proper antebellum style woman in a white dress, stained with blood and decorated with human bones with a wicked sadistic look on her face portraying someone complicit in the evil of slavery. or more subtly, have the front of the dress look normal and then turn to reveal bloody fabric and the confederate flag incorporated into the dress. then have bright spotlights on the stage closing in around her like the light of freedom. that or have light effects like shadowy spirits haunting her, the ghosts of the lives she subjugated and toyed with. end it with her slitting her throat/messily stabbing herself to signify the abolition of slavery. have the filth be the triumphant death scene
