I hear Keith Jarrett since the mid-80s. In the 90 years I have heard him live as a soloist. My favorite CDs are far ECM 827827-2 "Standards Live" from 1986, and "Tribute" with this line-up like this. It's the sound (including the familiar intonation of the wing), which makes more-so much joy I do not say. I do not need innovations of Keith Jarrett's like a cake which you like and do not want to have changed.
