Weird how these things happen. Checks and balances make it right.

In the best of Keith Jarrett's long-form Concert recordings—Bremen Lausanne, Köln, and most of all Bregenz München and the monumental Sun Bear—one hears the evolution, over unbroken spans of as long as 45 minutes, of a beginning musical germ. A mere rhythm or broken chord or simple cadence or single note, sometimes a full melody exquisitely arranged, opens what seems an infinite world of musical ideas, channeled or happened on or willed up out of the moment, then explored in depth and at length, all flowing into and out of each other—and into and out of jazz, blues, gospel, folk, Middle Eastern, Baroque, Classical, Romantic, and 20th-century styles (Ives, Bartók, Stravinsky). One gets the impression of a musician who has heard and played every kind of piano music there is and who, on a given evening, serially or simultaneously plays any and all of it. No one else has ever done anything like it.
