In a boundary-pushing collaboration between mother and son, Shayok Misha Chowdhury considers what is experimental about experimental theater. In this new play, the Obie-winning writer and director joins forces with his physicist mother, Bulbul Chakraborty. Chakraborty is obsessed with investigating the mystery of sand and how it flows, like a liquid, but then jams into a solid. Chowdhury is obsessed with his mother. In RHEOLOGY, they both grapple with running out of time as the artistic son challenges his scientist mother to a high-stakes experiment. Together, they move through rheology—the study of how matter moves—in a poignant meditation on love, loss, and vocation.
