The Whitney Museum of American Art has added one of Patty Chang's most consequential works to its permanent holdings. BANK, the Shanghai and New York gallery that represents the artist, announced on October 14 that the museum acquired Invocation for a Wandering Lake, Part 1 & 2, a two-channel video installation made in 2015 and 2016. The acquisition places Chang's work in one of the country's defining collections of twentieth- and twenty-first-century American art, which spans more than 25,000 works by over 3,500 artists.

The piece belongs to The Wandering Lake, an eight-year project Chang pursued from 2009 to 2017. Its first channel was filmed on the coast of Fogo Island, Newfoundland, where the artist kneels beside the carcass of a beached sperm whale and slowly washes it with a sponge and a bucket of water. The second channel moves to the opposite end of the earth: the shoreline of the Aral Sea in Uzbekistan, where Chang wades into the shallows and scrubs the rusted hull of a boat marooned on the dried seabed. The gestures are repetitive and unhurried, small acts of tending directed at landscapes and bodies that are already gone.

The project grew out of Chang's encounter with the Swedish explorer Sven Hedin's 1938 book The Wandering Lake, an account of his search for a migrating body of water in the Central Asian desert. Where Hedin tried to chart the lake's movement, Chang turned toward what its disappearance leaves behind: displaced communities, forgotten histories, and the way the loss of water reshapes land, body, and memory. The work's slow rituals of care, tender and, in the face of ecological collapse, impossible, have made it one of the defining pieces of her career.

Invocation for a Wandering Lake has traveled widely: the 11th Shanghai Biennale in 2016, Chang's 2017-2018 Queens Museum solo, BANK's Re-Configurations (her first solo in China) in 2017, and the Institute of Contemporary Art, Los Angeles in 2019. Its entry into the Whitney's collection cements its standing as a landmark of socially engaged video art.
