One of the most wide-ranging of all Keith Jarrett’s performances, “The Carnegie Hall Concert” almost amounts to an autobiographical portrait of the great improviser. Each of his two sets takes the form of a suite of songs, some intensely lyrical, others angular, turbulent, or probing. And the encores – no less than five of them – touch upon the blues and boogie-woogie, upon standard material (“Time On My Hands”), and even offer a new perspective on “My Song”, written for the Scandinavian ‘Belonging’ quartet and first recorded by Jarrett in 1977.
