Keith Jarrett launched into an improvisation that has not only conquered an audience of musicians but also the general public to directors who accompany their images of the famous part I of the concert in Cologne, including Nanni Moretti in "diary" . The CD takes about an hour, the tone sometimes leaves the jazz classic harmony prevail and metamorphoses into a symphony tone that could be taken for a kind of serialism. The last piece is a marvel of sweetness and a wonderful gift of musical life.
