Kaari Upson, an American artist whose uncanny sculptures, videos, drawings and performances probed the dim sides of domesticity and want, died on Wednesday at a medical center in Manhattan. She was 51.

The induce was metastatic breast most cancers, stated Claire de Dobay Rifelj, a director at the Los Angeles arm of Sprüth Magers, the gallery that represents her.

Ms. Upson, 1 of the most significant artists to arise from the vibrant Los Angeles art scene this century, gained early attention for “The Larry Project,” an open-ended phantasmagoria centered on the daily life of an unfamiliar neighbor of her dad and mom in San Bernardino, Calif., who experienced abandoned his McMansion. Doing the job from pictures, legal paperwork, diaries and pornographic magazines remaining powering in the residence, Ms. Upson spun an obsessive psychological profile, on the border amongst simple fact and fiction, of a stranger who experienced manufactured a minimize-amount Playboy Mansion on a suburban cul-de-sac.

Initially revealed at the Hammer Museum in Los Angeles in 2007, “The Larry Project” spiraled into a five-12 months series of big charcoal drawings, drippy painted portraits, and performances with a lifestyle-dimension “Larry” mannequin. The project’s compulsive reflections of Californian fantasies and nightmares constructed on the abject Americana of Mike Kelley, Paul McCarthy and other Los Angeles artists who emerged in the 1980s, as well as the personal obsessions of the French artist Sophie Calle.

“The Larry Venture,” neurotic and tender by turns, evolved into a substantially much more emotional, all-encompassing endeavor — in which the absent Larry, whom Ms. Upson in no way fulfilled, expanded into the artist’s muse, her lover, her persecutor and, in the end, her doppelgänger. By the stop, no clear difference was left among artist and matter the two had come to be doubles. A single drawing in the Hammer Museum show bore the phrases “I am far more he than he is.”

The venture ended in 2011 with a efficiency at a Los Angeles gallery at which she dragged a charcoal-and-wax mannequin of Larry on the walls and floor within a plywood dice until the effigy disintegrated, symbolically turning Larry’s entire body into dust.

In about 2013, she turned to casting mattresses, couches and other domestic objects in latex, urethane or silicone. By producing a mildew of the furniture and then spraying the mold with levels of resin, Ms. Upson produced marginally translucent sculptures that drooped or sagged off the wall, or in some cases stood awkwardly in the gallery as if bowing less than their own pounds. With these stained, crumpled ghosts of furnishings, as well as related performances on movie, Ms. Upson imagined Americans’ bodies as by some means indistinct from the houses they owned and the household furniture on which they slept, produced adore or died.

The resin sculptures ended up showcased in the 2017 Whitney Biennial and the 2019 Venice Biennale, and Ms. Upson’s artwork is in the collections of the Museum of Modern day Artwork in New York, the Museum of Present-day Artwork in Los Angeles and other big museums. The New Museum in New York staged a widely praised midcareer retrospective in 2017.

But Ms. Upson, after her early achievement, grew skeptical of the artwork world’s treadmill of demonstrates and gross sales, and aimed to carve out time to deliver with out a planned outcome.

“I’m not hoping to get to a concluded issue there is no finished level,” she stated in a 2016 interview for the artwork magazine Even. Somewhat than discrete artworks and exhibitions, she said, she chosen to build “a fragmented narrative that you can enter at any issue,” introducing, “It’s about in which the narrative cracks open up, and when something’s missing, I basically plant it with full fantasy: speculation, mirroring personas.”

Ms. Upson was born on April 22, 1970, in San Bernardino, to Karin (Kuhlemann) Upson and Bert Upson. (Her 12 months of delivery has frequently been incorrectly noted as 1972.) The landscape of the Inland Empire, and the ecological perils of wildfires and mudslides, formed her impressions of the solitary-spouse and children residence as a fraught and unstable point. Reflecting on her childhood in a 2017 difficulty of Job interview journal, she said, “I grew up in a frequent point out of anything coming from the outdoors that you could not management, and all the things could be absent at any minute.”

She went east to review at the New York Studio Faculty, the place she worked principally in portray. She returned to comprehensive her bachelor’s diploma in fantastic arts in 2004 and her master’s in 2007 at the California Institute of the Arts, in which she was motivated by Bérénice Reynaud, who taught feminist and psychoanalytic ways to cinema and movie.

It was for the duration of her time at CalArts that she initial entered the deserted, hearth-ravaged residence exactly where “Larry” experienced when lived and in which, in addition to his diaries and documents, she found mattresses strewn in practically each and every room. (A next fire, two years later on, ruined the house wholly.) “The Larry Project” grew out of her thesis at CalArts.

Ms. Upson on a regular basis employed general performance to infuse her artwork with more narratives of doubling and need. For “The Grotto” (2008-9), she built a fiberglass duplicate of the infamous poolside cave at Hugh Hefner’s Playboy Mansion, then made use of it as a phase set for hilarious, almost unhinged video clips of enjoyment-looking for, insecure Californians. The video “In Research of the Great Double” (2017) observed her crawling and crab-going for walks by tract houses in sprawling Las Vegas, like a demented parody of an HGTV exhibit.

Her most enduring operate may well be the resin sculptures. Flaccid shadows of beds and couches, in runny palettes of teal, mauve or orchid pink, they translated her engagement with suburban American domestic existence into placing totems of want and absence. They also experienced much more personalized significance, coming right after an original prognosis of cancer.

The sculptures grew to become attempts, she said in the 2016 Even job interview, “to reactivate the bed and the couch — they began to stand for pretty adverse items for me. It was a cult of invalidism. I was at a position when I was either heading to get up from one or die on a person.”

She is survived by her daughter, Esmé Earl Rudell her brother, Dirk Upson and her father. Her relationship in 2000 to Kirk Rudell, a television producer, finished in divorce in 2010.

Speaking to Artnet News in 2017 on the occasion of her New Museum retrospective, Ms. Upson pointed to an not likely inspiration for her perform: the vibrant orange “Idiot’s Guide” collection of textbooks, which she had included by the dozen into a big set up. These deal-basement manuals, on topics from quantum physics to gambling to wholesome associations, encapsulated for her the stress concerning mindful awareness and unconscious dreams, and what comes about when consumerism fills the hole.

“There’s no figuring out every little thing, and the guides are about not recognizing. But the accidental overlay of info can build new instructions,” she claimed. “Formally, I like to get the job done with materials the place I do not absolutely know what is likely to come about. As soon as I start out to learn a little something, I’m out.”
