The folk singer and Rock and Roll Hall of Famer was found unconscious in her home, said a statement on the Mitchell website. “She is currently in intensive care undergoing tests and is awake and in good spirits.”
It wasn’t immediately clear what illness she had.
Los Angeles fire officials said paramedics answered an afternoon 911 call in Bel Air, where Mitchell lives, and took a patient to the hospital. But they could not give details on her condition.
The 71-year-old singer-songwriter told Billboard magazine in December that she has a rare skin condition, Morgellons disease, which prevents her from performing. Still, she released a career-spanning four-disc box set last year and appeared at Clive Davis’ annual pre-Grammy party in February.
Mitchell has received eight Grammy Awards, including a lifetime achievement award in 2002. She was inducted into the Rock and Roll Hall of Fame in 1997.
Joni Mitchell was born Roberta Joan Anderson in Fort Macleod, Alberta, Canada and grew up in Saskatoon. She moved to Toronto after leaving art school, and later to Detroit with her husband of a year and a half, Chuck Mitchell.
In 1967, Mitchell moved to New York city, where she was part of the legendary Greenwich Village folk scene.
She began touring up and down the east coast, and saw her songs such as The Circle Game and Both Sides Now recorded by Buffy Sainte-Marie, Dave Van Ronk, and Judy Collins.
She later moved to southern California, and became a mainstream star with her famous song Woodstock — an anthem of the hippie era known both in the form of Mitchell’s own version and a cover by Crosby, Stills, Nash and Young.
Her second album, Clouds, was a breakthrough with such songs as Both Sides Now and Chelsea Morning, winning Mitchell the Grammy for best folk performance.
Her 1970 album, Ladies of the Canyon, featured the hit single Big Yellow Taxi and the era-defining Woodstock. The following year, she released Blue, which ranks 30th on Rolling Stone magazine’s list of the 500 Greatest Albums of All Time.
Mitchell has released 19 original albums, the most recent in 2007. The anthology released last year, Love Has Many Faces: A Quartet, A Ballet, Waiting to Be Danced, features remastered versions of 53 of her songs.
Her musical style integrates folk and jazz elements, and she counts jazz giants Charles Mingus and Pat Metheny among her past collaborators.
As with music, Mitchell taught herself painting as a child and has produced hundreds of works in ink, watercolor and acrylic.
