Hüseyin Umaysız is a theatre director and performance artist. He describes himself as a mountain man, a savage in modernity. Fascinated, he investigates the effects of performances in which the body is under pressure, vibrations become sound, and time-rhythm shifts.

In recent years, he has focused on the relationship between humans, nature and materials. He is currently researching the Munzur River in Kurdistan and felt, the first industrial fabric. He discovered that women used river water for yoghurt and bread yeast.

Inspired by this tradition, he investigates the relationship between the human body and the billions of bacteria that surround us. With the performance Gist (yeast) he lets the audience watch this process, in the form of a unique, sensory experience.
