About the Project


Keepers is a perpetual music installation based on Jakub Ciupinski's concept and design. Commissioned, created, and launched by Metropolis Ensemble in response to COVID-19, Flame Keepers runs uninterrupted in real time, twenty-four hours a day, seven days a week.

Invited artists are commissioned weekly to serve as musical custodians and creators, or Flame Keepers, tasked with supplying new original material every seven hours. As a result, the piece will evolve as an open-ended collective composition designed to run forever.

We intend the Flame Keepers experience to be a virtual bonfire shared by a group of strangers worldwide, a concert that never ends, made in, and especially for, times of hardship and social isolation.
