OT Series is a Berlin-based curatorial framework for sonic and artistic exploration.
Conceived and curated by Juan Orozco, the project unfolds through a constellation of series, each tracing its own logic, methodology, and territory — forms of practice that resist fixed categories.

It gathers recordings, performances, and sonic experiments shaped by the political, material, affective, historical, and technological conditions in which they emerge.
Each series becomes a space for listening — not only to sound, but to the shifting relations it invokes — where listening itself is questioned, expanded, and transformed, across evolving contexts and modes of practice.

 The first collection, Superficies Aurales [1–4], presents long-form experimental pieces — including solo works by Juan Orozco and collaborations with Eren Solak and Gustavo Obligado — released in digital format, as individual cassettes, and as a limited box set.
