Pianist Keith Jarrett, a pioneer in several musical realms whose efforts were met with near-universal acclaim, can no longer perform. His multifaceted career included jazz ventures with the likes of Art Blakey , Charles Lloyd and Miles Davis ; classical endeavors in works by J.S. Bach , Bartók, Pärt and American-Armenian composer Alan Hovhaness ; and, most famously, expansive solo improvisations, such as the iconic “Köln Concert” of 1975, one of the best-selling piano recordings in history. Now, sidelined by two devastating strokes, both suffered in 2018, that part of his life has come to an end. Yet, numerous recordings are still in the can, and ECM is beginning to roll out a series of new issues—including a splendid solo concert captured live in Bordeaux, France, in 2016, to be released on Sept. 30.
