Images of glowing light danced to a slow electronic beat, as an indistinguishable instrument radiated sound resembling flowing water.

No more than 100 people sat down in the darkened cavern in the northwest Iranian city of Qazvin, while listening to the tune played by the electronic musician, Saba Alizadeh, who came up with the idea to highlight the ongoing water shortage in Iran.

A century ago, it would have been impossible for the artist to entertain his audience there. The facility, common across pre-modern Iran, was originally built to store drinking water underground for local residents in Qazvin, 140km northwest of the capital Tehran.

But for years now, most of these reservoirs have dried up, turning the structures into relics of Iran’s past.

The brick-lined water reservoir, known as Ab-Anbar in Persian, is covered with a dome, protecting the stored water from evaporation and contamination. It is connected to a wind tower, known as badgir, which serves as a natural cooler of the water inside.

These reservoirs were so important to life, particularly in the desert areas, that they became integrated into communities in arid regions of the country.

Alizadeh, the musician, saw an opportunity to revisit these architectural icons, in an effort to raise awareness about the country’s water crisis.

“Metaphorically speaking, the concerts were a recollection of the water that did not exist there in the reservoirs any more,” Alizadeh told Al Jazeera.

“It is supposed to sound the alarm, reminding Iranians that in a place which used to be a depot for water, now there is only dirt.”

Recently, the research arm of the Iranian parliament warned that water shortage in the country could lead to social discontent. It added that by 2020, up to 80 percent of Iran’s more than 80 million people could face water scarcity.

‘Elegy for water’

So far, Alizadeh has performed his show, Elegy for Water, at reservoirs in the cities of Qazvin, Kerman and Shiraz. The 35-year-old musician plans to do more events in Kashan, Yazd and Isfahan, cities that in recent years have faced water shortages.

The water problem in these major cities has been exacerbated by poor infrastructures and government policies.

About 35 million Iranians, a little less than half of the total population, living across 334 cities faced water shortage during the summer of 2018, according to Iran’s Minister of Energy Reza Ardakanian.

Lack of awareness about the issue has further added to the problem.

“We are facing a severe drought … We don’t seem to pay attention to the things that are happening in this regard,” Alizadeh said.

“Perhaps this tour could be a very small gesture to remind people of water; so that they could appreciate it a bit more,” he said, referring to the wastage of water in the country.

Alizadeh came up with the idea of the musical piece in 2012, when he started to study music at the California Institute for Arts, after he finished his bachelor’s degree in photography in Iran. It was only much later, when he decided to perform the piece at dried-up cisterns to highlight the growing water problem.

Fusing music and religion

Zanjeer is mostly used during annual Ashura commemorations by Shia Muslims, swinging it against their back as an act of mourning the death of their third Imam.

Alizadeh installed a microphone at the end of Zanjeer’s handle to capture the granular sound made by the movement of the chains.

The rattling of the chains is then processed by a computer to become a sound that is reminiscent of that of flowing water.

“I wrote the harmonies within the sound of the water,” he explained.

The initial piece was completed with an overture that he wrote recently, turning Elegy for Water into a 40-45 minute-long musical number.

‘Nailed to my chair’

The performance includes visuals created by artist Siavash Naghshbandi, who collaborated on the project. The images were an artistic perception of the reflections of water. They were projected on the walls of the water cisterns.

Speaking to Al Jazeera, Naghshbandi referred to the “mysterious” quality of the forms that the flow of the water creates; as well as the irony of watching those visuals in a dried-up cistern.

“The images were projected on the ceiling. It was as if you saw the reflections of the water when you take a look above, knowing there is no water in the reservoir,” he said.

Roshanak Sajadian, a Tehran-based architect, took a two-hour road trip to Qazvin to watch the show.

“The combination of the concept, the music and the location turned this into a curious event,” she told Al Jazeera.

“It was as if I was nailed to my chair, wiping tears off my face as the music rose to a crescendo.”

Andreas Spechtl, an Austrian musician who collaborated with Alizadeh on the project, told Al Jazeera that the artist is “mourning the loss of water, while treating a highly traditional and religious device, Zanjeer, as an electronic instrument.”

“One could call it conceptual art. But it’s not that easy, because there are no answers and no great solutions in his work. He is not making a big case. No. He’s now and then dropping a question. And that’s the noblest thing you can say about art.”
