For Milan Design Week, Hidden Mountain presents Condominio, a sound installation created in collaboration with Furio Montoli inside Convey, an exhibition organised by Simple Flair in a 1970s Milanese building.

The project draws on the Jungian idea of the house as a metaphor for the psyche, a layered structure whose spatial levels correspond to levels of consciousness. The installation takes up this image and rereads it in sonic terms, reversing its direction: not a descent into the unconscious, but an ascent through the spectrum of frequencies.

The composition unfolds along the building's staircase by register. On the ground floor, lower frequencies build a dense, disorienting presence. As you climb, mid-range frequencies emerge, closer to the voice and to speech. On the upper floors, higher frequencies introduce a more rarefied, suspended quality.

The sonic material originates from a collection of vocal recordings shared voluntarily online by a varied group of participants, friends and family of the studio. Each voice carries clear traces of its identity: timbre, intonation, the recording device, the room, the duration, even the way each person responds to a minimal prompt like singing or vocalising into a microphone. Catalogued, analysed and organised by note and frequency band, these contributions form a collective choral piece in which singularities are not flattened but keep their own presence.

In this sense, the work resonates with its host environment: the staircase of a residential building, a transitional and communal space, close to domestic intimacy yet traversed by a shared dimension, where distinct identities coexist, intersect, and brush against one another.
