New York-based Tehching Hsieh has undertaken 18 years of continuous performance. Known for dedicating long and precise periods of time to fully immersive projects, the Taiwanese-born performance artist's lengthy works span everything from spending a year locked in a small wooden cage to thirteen years making art not meant for public display.

In a new profile, New South Wales-based directors Versus captured perhaps the most enduring of Hsieh's pieces: One Year Performance 1980–1981 (Time Clock Piece). The project saw Hsieh punch a time clock every hour on the hour for exactly one year, each time recording a single frame for his film that condensed the year into six minutes of footage. Shaving his head at the start of the extensive project, the artist's growing locks became a visual marker of passing time, the central theme running through his body of work.
