As part of Keith Jarrett’s rather extensive project on the works of the Cantor of Leipzig, an interpretation on harpsichord of Livre I from J. S. Bach’s The Well-Tempered Clavier was recorded in February 1987 and released in 1988. The recording dates from the same time as this new piano version by ECM New Series recorded 7 March 1987 in Troy Savings Bank Music Hall. Of the same fluid drive in terms of the discourse, it holds an irresistible energy and is a particularly welcome interpretation of these invigorating and interpretable fugues (in C flat Major). Everything seems to dance and be in movement (D Major). The same feelings found throughout the polyphonies of pianists such as Tatiana Nikolayeya and Samuel Feinbeg or even a harpsichordist like Gustav Leonhardt are not present here. For Keith Jarrett, Bach represents the triumph of structure, and he plays Bach above all to confront one of his own artistic missions: polyphonic elaboration. The works of the Thomaskantor work as a medium for his own musical creativity as a jazzman and improvisor. The poetry and emotion are nevertheless ever-present. This is a version that will give real pleasure to all lovers of Keith Jarrett’s, allowing the comparison of two interpretations realized within two weeks of each other. Pierre-Yves Lascar/Qobuz
