This isn’t a great piece in Keith Jarrett terms; he often improvises extremely beautiful and complex pieces, and the last album of his I got still renders me speechless.
This is from 1984 in Tokyo, and is pretty simplistic, if virtuosic. I’m mainly posting it for you, Will and Syd, so you can see what the man looks like playing.
Update: it may be structurally simple, but this is totally fucking awesome. The different tempos, the joy, the propulsion. I love it.
