In my opinion presented Keith Jarrett hereby first time his matchless improvisational style in solo concerts in Europe before. Since the publication of these two concerts, I'm a big fan of the musician and had first as LP and later on CD all his solo concerts and in addition also a number of other records and CDs, on which he plays for. B. with saxophonist Jan Garbarek purchased. But the solo concerts point to the actual fine art Keith Jarrett to elicit completely new sounds the piano.
