J. Alexander Diaz’s sound is de rigeur for serial killing. 
Lighting, sound, and set design (by Cate DiGirolamo, J. Alexander Diaz, and Alfred Schatz, respectively) created an engrossing, almost claustrophobic environment that pulled the audience into the scene, effectively portraying the proverbial walls closing in around the characters onstage.
