On Tuesday, 9 February 2016, Keith Jarrett returned to Carnegie Hall for a solo performance of spontaneously improvised music. My review of the concert is now available at All About Jazz here.

Would like to see this show released! Thought it was his best effort at Carnegie in some time. Hope ECM + Keith make it happen. Audience was best it has been in a while at Carnegie, despite a few hiccups.
Yes, I agree! Despite my minor quibbles, the music was fantastic.
