The Evolution of Sound

A live-streaming perpetual sonic art installation created by Metropilis Ensemble and commissioning a new weekly contributor.


This Week's Curator

Sydney Spann

Sydney Spann, originally from Baltimore, MD, is a sound artist and musician based in New York. She works with synthesis, chance operations, recursive compositional processes and voice to intervene within a personal archive of field recordings, culminating in long form compositions and improvised performances. Her music engages the private experiences that shape public spaces, and the affective dynamics within childcare work. She has released albums with Ehse Records (Baltimore), She Rocks! (NYC), and Reading Group (NYC), with a full-length release forthcoming on Recital in 2022. She has performed at the High Zero Festival of Experimental Free Improvised Music, Bar Laika by e-flux, Performance Space New York, Center for Performance Research, Cafe OTO (London), KM28 (Berlin) and in diy spaces and galleries throughout the US. Recent works for streaming include Sending up a Spiral of on Montez Press Radio and Attached/Detached (partial disappearance) for ISSUE Project Room’s With Womens Work Series. She is a 2022 Artist in Residence at ISSUE Project Room and an MFA candidate in Music/Sound at Bard College.

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.
