Cynthia Plaster Caster, the artist known for casting rock musicians’ penises, has died aged 74.

Her representatives confirmed her death on April 21, noting that she died in Chicago after a long illness.

During her career as an artist, Cynthia Albritton has done celebrity castings for artists like Jimi Hendrix, Pete Shelley of the Buzzcocks, and Dead Kennedys frontman Jello Biafra.

Born in Chicago in 1947, she attended art school in the 1960s, where she was asked to create a plaster cast of “something solid that could hold its shape”. Instead of going for something typical, Albritton decided to turn his attention to the leaders of his favorite bands.

Jimi Hendrix was his first famous subject, having agreed to be cast while on tour in Chicago in 1968. Hendrix was followed by two members of MC5: Wayne Kramer and drummer Dennis Thompson, although the penis cast of Kramer did not go as planned.

“He got the container that wasn’t designed for mixing alginates,” she said in an interview with The Chicago Reader in 2002. “And if you mix it the wrong way, it hardens prematurely. He took before he could push his cock all the way into the mold – only the head went in.

She continued: “Wayne is fully aware of what he has. He has nothing to prove to the world.

Although she never had it as a subject, Gene Simmons wrote a song called “Plaster Caster” for KISS’ 1977 album “Love Gun”, which included the lyrics: “The plaster gets harder and my love is perfection / A token of my love for his collection.”

Albritton befriended Frank Zappa, then moved to Los Angeles, and although he supported his art, he refused to participate in the art. When his apartment was burgled in 1971, Zappa and Albritton gave more than two dozen casts to Zappa’s legal partner, Herb Cohen, for safekeeping.

When she tried to retrieve them, it took longer than expected, which ultimately resulted in a court case in which Albritton retrieved all but three casts.

She held her first exhibition of plaster casts in New York in 2000 and continued to exhibit work at MoMA PS1 years later. She was also the subject of a documentary in 2001 plaster caster by Jessica Villanes.

In her later career, Albritton included male filmmakers and female artist breasts in her work, with names such as Peaches, Karen O and Stereolab’s Lætitia Sadie being part of her collection.
