Beautiful harmonic "small" Music

For me, a beautiful soft music.
Interestingly, the development of Keith Jarrett to track from the 70s until today. Certainly, many rough edges have rounded. But that's in such artist who lives with the music, but normal.
The Cologne-concert should fit into the time in which it was created. His music has been a great development behind it, it has matured and remained beautiful. But it has changed, and that's good ..........
