The Koln Concert 2-LP / gatefold sleeve / booklet / printed signature - the groundbreaking recording of Keith Jarrett's improvised solo concert at the Cologne opera house - has attained legendary status since it's 1975 release. An iconic album and an essential document of the era, few live recordings in any idiom have been celebrated as widely. In the liner essay included in the 50th Anniversary Edition of the album, the concert's context is outlined in detail. Recorded on January 24, 1975 and originally released on November 30 the same year, The Koln Concert was produced by Manfred Eicher. For the 50th anniversary, the special edition 2-LP is released in a high-quality tip-on-gatefold sleeve with a glued-in, 8-page booklet featuring a new liner essay in German and English, as well as original and new photos. Includes an art print with a photo and printed signature by Keith Jarrett.
