Like an architectural flute hiding in the urban fabric, the ancient water tower of Zurich will once again come alive with the sound installation The Whistle. The work is a site-specific intervention by the VACUT collective (Voices Against Corruption and Ugly Trading), initiated by Gilles Aubry in collaboration with Ale Hop, Aya Metwalli, Gabi Motuba and Sabina Leone. For the third event of OTO SOUND MUSEUM at the Wasserturm in Zurich, the voices of The Whistle will pass through the silent body of the tower to interrogate the near and distant realities we live in.

The installation The Whistle features voice recordings presented inside the Schanzengraben water tower in Zurich, audible from the surrounding public space. Informed by data leaks and NGO reports highlighting Switzerland’s involvement in international money laundering, tax evasion, and predatory extraction of raw materials,
the work seeks to address the affective cost of racial capitalism from a situated perspective. The VACUT Group (Voices Against Corruption and Ugly Trading) was formed to this end, gathering sound artists and musicians from countries involved in dubious business activities with the alpine nation.

The work relies on voice as an embodied manifestation of perceived social and environmental injustice. Each performer engages with a number of sources documenting corruption, land grabbing, human exploitation and environmental devastation in their home countries, along with their own perception of such phenomena. They respond to this experience through vocal improvisations in the course of recorded sessions. Assembled into a composition, the voices blend with the local ambient sound in Zürich. Listening becomes a matter of participation, empathy and accountability, an invitation to attend to one’s boundedness to near and distant realities.

The project further interrogates existing acoustic representations of Swissness, a term rebranded in the 1990s for marketing purposes, largely associated with attributes of fairness, precision, reliability, political stability, naturalness and cleanliness. An early
example of Sonic Swissness (Oehme-Jüngling 2014) can be found in the composition “Symphonie Les Echanges” by Rolf Liebermann, created for the 1964 Swiss national exhibition in order to introduce the visitor to the interaction of the economy in a novel way. Another instance can be found in the “Sound Tower” installed in Bienne by Andres Bosshard for Expo.02. Essentially a streaming dispositive for immersive aural experience, Bosshard’s Klangturm offers a perfect metaphor for neoliberal soundscaping—smooth, consumption-oriented, and depoliticized. Following the rejection of the Responsible Business Initiative by a majority of Swiss voters in 2020, conversations on Sonic Swissness certainly deserve an update. This imperatively should include voices from Switzerland’s partner countries, who can attest of the actual human and environmental cost of Swiss wellbeing.

SOUND TURM program 2022
Website www.oto.museum

OTO SOUND MUSEUM is a nomadic museum that produces, presents and collects sound works by contemporary artists from different backgrounds, geographies and generations. The museum was born digitally as an iconoclastic environment and a utopian architecture on the platform. It is also used to travel across different places in the physical realm, transforming its identity along the way.

ZAIRA ORAM is a curatorial collective focused on experimental displays and interdisciplinary projects. Her practice involves research on visual art, performance and sound art and the creation of networks between different disciplines and areas of studies. Her main research threads are migration, contemporary narrative and border experiences. Zaira Oram has an open identity: she travels and transforms herself. The collective was initiated by Francesca Ceccherini and Eleonora Stassi, and expanded with the participation of Chloé Dall’Olio, Camille Regli and Elisa Bernardoni.

WASSERTURM – historical traces
Among the few places that survived the new Zurich urban plan – whose history remains unknown to most citizens and tourists – the Wasserturm was built in 1724 in the Talacker district with the aim of bringing water to the houses, local businesses but also to the fountains placed in the surrounding baroque gardens. Indeed, the district was lacking of independent public water supply. Hence, a group of citizens decided to join forces for a common mission: build a water tower that would distribute this primary good to people and activities in the area. For nearly 200 years, the water tower fulfilled its function, first through a water wheel and then through its transformation into a steam technology. Acquired by the city of Zurich, it later fell into disuse. Today it houses a center for sports activities.
The tower still stands with its white-green verticalism above the waters of the Sihl looking at the Old Botanical Garden. It is characterized by an octagonal plan rising four floors and a curved copper helmet roof that resembles the shape of an onion. Its symbolic presence and its silent memory, hidden between contemporary buildings, make this place of significant historiographic, anthropological, social and even artistic interest.
