Assemble is an immersive theater experience that includes secret locations, apps, audio tours and choosing various paths for each member of its audience to pursue a unique adventure. The journey begins when the rendezvous point is sent to ticket buyers the day before the performance. Some technological know-how is required, too, since audience members must download a custom-made app to their cell phones, listen through earbuds, and record actions they have performed during the show. At the check-in, a code is given to participants to enter into their phones. From there, the performance begins, and viewers are off to the clandestine space—a box store big enough to accommodate shifting locales—in Brooklyn.
