In order to stay true to the high audio quality of the original recordings, the two outstanding sound engineers entrusted with the task of re-mastering the recordings at MSM Studios in Munich decided on a special approach: Dirk Sommer of Hifi Statement Netmagazine and Christoph Stickel, who was responsible for the re-mastering of numerous ECM re-releases (among them Keith Jarrett‘s “Köln Concert”), committed themselves first and foremost to remaining absolutely faithful to the originals. They retained all extraneous sounds present on the original live recordings, including the applause of the living-room audience. Working exclusively with analogue equipment, Sommer and Stickel carried out minimal restoration on the grand piano sound, subtly boosted the bass and lightly reduced the attack of the cymbals where necessary. This is something that had not been done on previously released CD and SACD versions. To put the cherry on the cake, the carefully optimised recordings are now being released on 180 gr vinyl.
