MUSTAPHA’S BRIDE and MEDICINE SHOW may seem an unlikely pairing, but these short plays are companion pieces. One dark; one light; they explore what happens when you tumble down the rabbit hole, and find yourself in a world that’s upside-down. The old rules don’t apply, and your future may depend on how fast you learn the new ones. Each play has a theatre festival pedigree, and were signature pieces for Sokoloff’s late performance group, the Aggravated Assault Ensemble.
