But Sill, who had a sad, strange life and recorded some beautiful, haunting, playful, inventive music through her tumultuous time, is not a name you hear very often these days.
Sill is often described as looking like a librarian. Her voice was quiet and fragile yet powerful. And her lyrics are often inscrutable, or at least Dylan-esque in their complexity and depths. The music was heavily influenced by Bach. The vocals were often layered and over-dubbed - her own voice, on top of itself several times. It's early 1970s, woman singer-songwriter, but very orchestral, complex and lush.
The clip down below - of her singing The Kiss - might remind you of other folk-influenced female singer-songwriters of the early '70s. But you can't say it's typical, not when you listen to something as upbeat and playful as perhaps her best known songs, like Jesus Was A Crossmaker or Crayon Angels.
Her voice is incredibly warm and affecting, quietly optimistic. Which is something given her struggles through life.
She was signed to the Asylum label in the early 1970s - the label that David Geffen would use to launch the careers of the greatest singer-songwriters of the era.
But Sill only recorded two albums (now considered lost classics) before addiction, mental illness and a terrible series of bad choices took their toll.
Sill was a chronic heroin addict from her late teens. And had a string of arrests, including several for prostitution and armed robberies of convenience stores in Ventura, California, before she was into her early twenties.
"I did heroin with gusto because I wanted to escape my torment and misery,' she told Rolling Stone in 1972 of her three-year addiction. 'But then I figured if could maintain that kind of habit that long, the willpower I'd need to kick it would be a cinch.'
She did kick heroin - but that was only one of the many problems which threatened to derail her life and constantly thwarted her attempts to build a career.
Her childhood was pretty chaotic - her dad, Millford Sill was, variously, an importer of exotic animals for movie work, part-time bar owner and full-time drinker. Sill grew up in her father's bar, and when he died early in her life, her mother married an animator best known for working on Tom & Jerry cartoons. It was a chaotic, bohemian, substance-driven. Her father, brother and mother all died when she was still in her teens.
However, she kept a strong sense of faith and spirituality throughout her life - sometimes saying that she wrote songs that "were aimed at persuading Jesus to give people a break".
By the time she died from drug abuse in 1979, she had long been forgotten. Her once intense relationship with David Geffen broken, which left her very bitter about the music industry.
Judee Sill could have been a Joni Mitchell, today she is not even a Nick Drake - another fragile singer-songwriter of the era who died tragically young but is today revered.
Few people really remember Judee Sill, which is a great shame, as she had a kind of genius.
I would heartily recommend checking out her two released albums and the collection of recorded but not released in her lifetime songs.
Also - there's a very good BBC4 radio doc about her - which you can listen to by clicking on above.
