American jazz pianist Keith Jarrett will probably never be able to perform in concert again, partially paralyzed by two strokes, he explains in an interview published Wednesday by the New York Times.

"My left side is still partially paralyzed," explains, for the first time, the 75-year-old musician, after two strokes in February and May 2018.

"I am told that the most I could get with my left hand is the ability to hold a glass," he laments.

Since then, he has only played the piano a few times, playing only with his right hand.

"I don't know what my future is supposed to look like," he told The New York Times.

"I don't consider myself a pianist today."

Jazz legend Keith Jarrett has been at the forefront of the movement since the early 1960s, and has collaborated with reference artists such as Miles Davis, Art Blakey and Jack DeJohnette.

His work around improvisation has led him to give totally improvised solo concerts, which have largely contributed to his reputation as a brilliant virtuoso.

“I feel like I'm the John Coltrane of pianists,” he told The New York Times, leveling off with the saxophone monster.

What may be Keith Jarrett's last concert dates back to February 2017, at Carnegie Hall in New York City.

If he has recorded several albums in the studio, the native of Allentown (Pennsylvania) is best known for his concerts, his clear-sounding playing and his facial expressions, in particular his head overly bent over the piano.

“Today, I can't even talk about it,” he says of the possible end of his stage career.
