The opening of klub katarakt brings together artistic creation, learning, and collective experience. Conceived as a montage of works composed by members of the Orquesta Experimental de Instrumentos Nativos (OEIN), the programme also includes participants from the instrument-building and performance workshops held in Hamburg, making the concert both the culmination and the expansion of a shared process.

Rather than presenting a sequence of separate pieces, the concert unfolds as a continuously transforming sonic organism. Sounds move through space, overlap, approach and recede, exploring different forms of listening and different relationships between performers and audience.

One of the central principles underlying the concert is the Andean concept of the tropa: an ensemble made up of multiple related instruments, distinct from one another yet belonging to the same sonic family. Unity does not emerge from uniformity, but from the interaction of similar voices and from their subtle differences in timbre, tuning, intensity, and spatial position. Each instrument carries an individual voice, yet reaches its fullest meaning only in relation to the others.

From this perspective, the concert imagines space as an extension of the instrument and the ensemble as a mobile architecture of sound. OEIN performers and musicians who have taken part in the workshops become part of the same sonic fabric, producing a music organised not only from the stage, but through movement, distance, resonance, and mutual listening.

The result is less a concert understood as a finished object than a collective situation: an expanded tropa, temporarily formed in Hamburg, in which different experiences, bodies, and instruments intertwine to create a single field of sound.
