From pollution and climate change to a soaring population that bleeds into available resources, humanity has officially entered the Anthropocene period. This era witnesses the alteration of the Earth's surface, atmosphere, climate, oceans, and lands as a result of collective human activities, causing biodiversity to drastically decline by 60 percent from 1970 to 2017.

Sebastien Leon's sound sculpture The Diffracted Symphony, inspired by the rib cage of a whale washed ashore, plays an altered version of Verdi's Requiem as a funeral mass for the biological state of the world. The recording used is the Dallas Symphony Orchestra's 2014 performance conducted by Jaap Van Zweden. Leon pleads for us to recognize that the challenge of our time is for humanity to understand its power for both destruction and preservation, and our urgent need to act as the caretakers of the Earth's balance.

The Diffracted Symphony is exhibited at NorthPark Center, surrounded by five Hammering Men by Jonathan Borofsky.

"I tremble, and I fear for the judgement and the wrath to come, when the heavens and the earth shall be moved. The day of wrath, that day of calamity and misery; a great and bitter day, indeed." (Extract from Verdi's Requiem)
