I have just read that jazz pianist Keith Jarrett will not be performing live any more, indeed has not done so for some time. He had two strokes back in 2018, the last year he released an album, and apparently he is simply not able to use one hand. He does not wish to perform with only one hand.
I saw him once live, in 1967 in the Memorial Union theater at UW-Madison, when he was playing in the Charles Lloyd Quartet. He got attention then for reaching over and directly playing strings on the piano with his hands. That was before he began doing his famous live solo albums or performing with his own group. Apparently his best selling albums, which I read is one of the greatest selling jazz albums ever, is the 1975 Koln Concert, which I have always loved a lot. He is 75 years old.
I note that my youngest daughter, Sasha, is a composer now out with 12 albums. She has long acknowledged him as an influence on her work and admired him greatly. In any case, this is sad news as far as I am concerned, viewing him as the finest living jazz pianist.
