We usually try to ignore latency (the delay between live sound and transmitted sound) in virtual concerts...but what if it's an integral part of the music?

Join American Composers Orchestra (ACO) on Oct 23rd for a hybrid in-person and virtual concert featuring works by two composers who experiment with latency and technology in their music, and a third interactive work through which we welcome one another into a collective landscape in which all sounds become music.

You don't have to be in NYC to attend. Just join us online!

Ray Lustig's Latency Canons calls for multiple quartets and an orchestra to perform together while spread out across the world. Trevor New uses technology to manipulate latency for remote musicians in his newly commissioned work, Cohere. Pauline Oliveros' Environmental Dialogue invites us to hear and respond to sounds both within our own space and in those shared by participants near and far.

Reserve your spot ($5 for this virtual concert) to receive the livestream link via email 24 hours prior to the event.

Music will begin promptly at 2:15pm EDT.

This groupmuse is co-presented by ACO and Groupmuse Foundation

Pauline Oliveros -- Environmental Dialogue (1974)

About the pieces:
Ray Lustig's Latency Canons, commissioned by ACO in 2013 and developed over a series of workshop performances before being premiered at Carnegie Hall that year, calls for multiple string quartets and ACO to perform together while spread across the world. The New York Times described the piece as, “a surreally beautiful, contrapuntal soundscape.” Lustig says, “In the spirit of using the problem as its own solution, Latency Canons incorporates technology’s limitations as the central idea. Musicians in different places play simple lines together using ordinary video-conferencing software, and the random blips freezes, and delays themselves create a counterpoint of beautiful, unexpected relationships, like echoes in a digital cathedral that wraps around the world. Latency Canons poses the question of how we make music together in our world, how that may be changing, and what this will mean for the musical experience. Our technology is drawing us closer and closer together in so many ways, and the attitude of this work is one of communion over distances.”

Trevor New uses technology to manipulate latency for remote musicians in Cohere 1. New says, “I want the audience to experience the ways we are connected by creating a digital space for us to see, hear, and feel interactions with others, whether they are next door or around the world. To achieve this experience, I am using Clean Feed to achieve low-latency performances. With it, I capture sound being played from different locations around the world and remove the latency effect by matching up the sounds into a single downbeat.” 

Pauline Oliveros' Environmental Dialogue invites the audience to hear and respond to sounds within their own space as well as the communal space shared by participants near and far. Oliveros published Environmental Dialogue in her Sonic Meditations collection in 1974. To perform the work, participants gather at a specified location. Then, Oliveros writes, “as each person becomes aware of the field of sounds from the environment, each person individually and gradually begins to reinforce the pitch of any one of the sound sources that has attracted their attention.…The result of this meditation will probably produce a resonance of the environment.”

A surround-sound music experience, Raquel Acevedo Klein’s Polyphonic Interlace invites participants to travel amidst a sea of voices emerging from several directions. All are welcome to play the piece’s musical tracks from their smartphones or speaker devices following a countdown at the start of the event. Music made entirely of Klein’s voice emanates from the house speakers and participants’ devices, transforming into a sonic tapestry of stories from across New York City at the cusp of the reopening. The tracks can be accessed at

Chris Kallmyer’s All Possible Music is a collection of speculative scores that describe all of the music that could ever happen. The piece explores the contextual nature of music, encompassing both real and imagined sounds to describe a world that is mundane, spectacular, sometimes humorous, and always alive: a blissful symphony for an audience of careful listeners; dance floor hits in a cabin set deep in the woods; visionary drum machines that heal the earth and its people.

Thank you all for joining this special virtual groupmuse tomorrow! On behalf of ACO, here are some additional details before tomorrow:

1. If you're fluent in remote music collaborations, and want to contribute (sound only) to the works by Trevor New and Pauline Oliveros, please fill out this form to receive an invitation to Cleanfeed: [DEADLINE: 12pm ET, tomorrow!]

2. For first-time users of Groupmuse: You'll see on our website and emails that Groupmuse strongly encourages audiences to pay musicians. This is because Groupmuse events are usually organized directly by musicians and hosts who hold concerts in homes, backyards, parks, and on rooftops. If you're used to Carnegie Hall concerts, Groupmuse is different because there is a reservation fee ($5) followed by a 'suggested donation' to directly show our appreciation to the musicians and ACO. This is Groupmuse's way of inviting in audiences who wouldn't normally step foot into a big concert hall. ("A little house concert-party? Sure!")

3. If anyone has any questions about Groupmuse, ACO, or Cleanfeed, Mann-Wen Lo will be on Zoom to help between 2:00pm - 2:15pm ET tomorrow. This Zoom link will be sent with the YouTube link, one hour prior. She will be in the Zoom throughout the live YouTube to provide technical support.
