One cannot express in words the beauty of this music. It is utterly raw, coming straight from the heart, a work of sheer genius. Whilst many pieces of so-called piano jazz easily lend themselves to the background of an occasion, the Koln Concert demands constant attention; with all of its changes in tempo, key, style and melody, the listener is enticed into the music, eagerly awaiting the next delicate keystrokes. Indeed, rather than being required to glean the often precious-few moments of brilliance from much music, with Keith Jarrett at the piano, the listener finds these instances thrust upon them every few seconds!
If you concentrate on the music for just a minute, you will find melodies which would ordinarily be the core of a piece, but which in this situation are simply played fleetingly, only to be replaced by yet another gorgeous tune.
I highly recommend this music to absolutely anyone; you do not have to be a jazz-lover to appreciate it! Even if you have never listened to this genre before (I am still unsure as to what "this genre" actually is!!), I sincerely appeal to you to give it a go! I promise you won't be disappointed!
If you do decide to purchase this album, and enjoy it anywhere near as much as I have, may I also recommend the Sun Bear Concerts, the Paris Concert, and Live at Carnegie Hall for more of the same! Jarrett has also played in a jazz trio, with Gary Peacock and Jack DeJohnette, and their music is also excellent. Other jazz pianists who I have found to have a similar touch include; Brad Mehldau, Bill Evans and Michael Wollny, although their music tends not to be improvised.
