Underground Reservoir Becomes a Musical Instrument

The Poughkeepsie Cistern held 5 million gallons of water. The space is about 150'x250' (36,000 SF) with a 21' high ceiling. 180 concrete columns 13'

Sometimes musical revolutions are born not in studios, festival stages, or new technologies.

Instead, they emerge from spaces that have been silent for decades.

In the American city of Poughkeepsie, an abandoned underground water reservoir built in 1924 and decommissioned in 2021 has unexpectedly become one of the most unique musical spaces of the new era.

For nearly a century, this site held water. Today, it holds sound.

The space, covering approximately 36,000 square feet with hundreds of concrete columns and ceilings over six meters high, creates a unique acoustic: sound can persist here for up to 14 seconds.

By comparison, the reverberation in a standard concert hall lasts about one to two seconds.

Here, a single note does not disappear. It continues to move. It returns.

It layers upon itself. It is almost like a living memory of sound. This completely changes the nature of musical performance.

The musician here does not just play an instrument. They play in concert with the space. Every pause becomes part of the composition.

Every breath is a musical gesture. And the listener stops being just a spectator.

They find themselves inside the instrument itself.

This is exactly how the creators of the MASS Design Group project describe the experience, viewing the reservoir as a new venue for sound and light performances.

Music behaves differently here. It is in no hurry to fade away.

It lingers in the air, echoing back from concrete columns, layering upon itself and transforming silence into part of the composition.

In such a space, music ceases to be a linear event. It becomes an environment that surrounds the individual.

It is no longer the familiar concert format where the stage is separate from the audience. Here, the space itself becomes a co-author of the performance.

What does this event add to the planet's soundscape?

For nearly a century, this reservoir held water—its movement, depth, and reflection.

Now, it holds sound.

And perhaps this is where the striking symbol of a new musical era lies:

The future of music is born of more than just technology. Sometimes it is born where the space itself resonates.

Not every instrument is made of wood, strings, or metal.

Sometimes the space itself becomes the instrument. And then music stops simply sounding.

It begins to surround, reflect, and literally encompass the person within itself.

And perhaps the most extraordinary concert spaces of the future will not be those with the most technology. Instead, they will be where the space itself sings.
