LAMENTATIONS: Assemblage 1 

LAMENTATIONS: Assemblage 2

LAMENT FOR UR.
Assemblages from the city that is no more.

[Ongoing project, first public performance planned for Sept. 2025, Warsaw ]
 

About:  https://ewatrebacz.com/lament

Collaborators: Ewa Trębacz (composer & digital artist) and Anna Niedźwiedź (voice, cultural anthropologist).
 

Project based on decoding of an ancient Sumerian text (The Lament for Urim) through creative interpretation, machine learning, spatial manipulation and transcoding between various media. In addition to the textual layer, the project focuses on the sensory and spatial dimension of sound and its power co-creating mourning rituals.
 

Assemblages: fluid, accidental, unique moments in time
 

The concept of assemblage is related to the interpretation of reality through the category of momentarily created and unique systems, which in turn create and generate something new themselves, but basically they are ephemeral, fluid, a bit accidental and unique.

Assemblages are also about going beyond the anthropocentric perception of reality and emphasizing the relationality of people, animals, bodies, space, plants, objects, various matter and its various textures, machines and technologies, etc. It is also an indication of non-discursive, performative and embodied elements of reality, and a turn towards interaction and broadly understood ecology.  Continue...
