Already in less than 72 hours, APTP’s home theater and ensemble has transformed—school desks fill the building, furniture is dispersed across the theater, APTP teens interact with rooms and objects as though they are fellow actors, and the entire Eugene Field Park field house (which houses APTP) is evolving into a multi-floor, multi-room performance space. This week, APTP hosts New York’s Third Rail Projects to learn the art of immersive theater. By Saturday (less than 72 hours from now), APTP and Third Rail will reveal the original 40-minute performance experience they have co-created in just five days.
