Collaborative Performances in Extended Reality


RECONTRE: a meeting, an encounter, a fight,  a game, combat...

- series of collaborative performances and human-machine interactions, connecting the worlds of immersive sound, performing arts and experimental Extended Reality.

DXARTS Spring Concert:

Hyper-Realities and Ephemeral Orbits

Meany Center for the Performing Arts
Katharyn Alvord Gerlich Theater
University of Washington Campus in Seattle 

 

Hyper-Realities and Ephemeral Orbits, May 15 2024

Laura Luna Castillo - XR environment design
Carolina Marín, Ashley Menestrina - movement artists
Daniel Peterson - live sound processing and diffusion
Ewa Trębacz - violin, Ambisonic sound archive
 


An interwoven virtual and physical space is created and traversed through VR trackers which bind the position and corporeality of the performers with virtual objects, translating their position into an invisible reality of sound clusters and spatial sonic arrangements.

The familiar, the bearable chaos and illusions of order unfold across technologically mediated hyper-realities, temporalities, and mnemonic worlds. Interactions and reactions occur across choreographies and spatial arrangements, binding the virtual with the real in unexpected knots and impossible behaviors.

RESEARCH LABORATORY

All Coding is Always Transcoding

The idea of these performances emerged during a week-long research laboratory in Spring 2024, held at the Meany Studio Theater, University of Washington.

Research Lab, Meany Studio Theater, University of Washington

TEAM

Laura Luna Castillo - XR programming, wearables set-up and ML
Daniel Peterson - Ambisonics, DSP and ML 
Ewa Trębacz - Ambisonic sound sources / sound archives
Maria Thrän - Documentation and Stage Manager


PERFORMERS

Ewa Trębacz - violin
Carolina Marin, Derek Crescenti, Emily Schoen Branch,
and Ashley Menestrina
- movement artists

 

This research laboratory invited participants from Drama, Dance, Music and DXARTS departments at the University of Washington, to test and explore Extended Reality systems for the formulation and implementation of performative scores and interactions for human-machine improvisations. It made use of a series of accessible and interchangeable algorithms that transform off the shelf, consumer available devices into tools for creative research beyond their intended uses or industries (e.g. gaming industry, surveillance and robotics).

SPAM New Media Festival 2024

Georgetown Steam Plant - Seattle 

 

Josiah Boothby - French horn
Laura Luna Castillo - XR environment design & visuals
Leanna Keith - flutes & movement
Ashley Menestrina - movement artist
Daniel Peterson - live sound processing and diffusion
Ewa Trębacz - violin, Ambisonic sound archives
 


This collaborative immersive performance brings to life a sound archive based on Ambisonic recordings realized in unique acoustical spaces of historical significance in Washington State. These spaces include WWI era bunkers in Fort Worden, and an abandoned nuclear plant in Satsop, Washington - inside its monumental cooling towers and the reactor building.

The original sounds were created by Josiah Boothby (French horn), Leanna Keith (flutist) and Ewa Trębacz (violinist and composer), through their improvised sessions in these spaces, recorded and processed in Ambisonics by Ewa Trębacz.

This initial material became a fragmented archive of sound sources, brought into another abandoned industrial place of significance in the Seattle area - the historic Georgetown Steam Plant.

An archive of sonic fragments was explored in live performance using room-scale VR, motion capture and positional trackers worn by performers in a 3D environment designed by Laura Luna Castillo, and processed live by composer Daniel Peterson. Movement artist Ashley Menestrina triggers sounds in the virtual space in a dialogue with the musicians, who also activate sounds and create new sound events in real time.
