Hans-Eberhard Dentler, a graduate medical physician but also an out-standing cellist and pupil of the renowned Pierre Fournier and founder of a Bach Society in Italy, has occupied himself with this opus over the course of many years. Because he finally wanted to realise Bach's score in a manner true to its spirit and sound, he found a concept for his ensemble "L‘Arte della Fuga" that unifies its more profound scholarly background with practi-cal musical and artistic aspects. The puzzle of this work can only be solved when one grasps its rootedness in the sphere of Pythagorean musical thin-king. Dentler's edition, scored for violin, viola, violoncello, double bass and bassoon in an utterly well thought-out arrangement of movements will soon be published by Schott Verlag in Mainz. It is sonically realised here on an extensive triple LP set as well as on a double CD.
